	abstract = {Bis(maltolato)oxovanadium(IV) (BMOV), and its ethylmaltol analog, bis(ethymaltolato)oxovanadium(IV) (BEOV), are candidate insulin-enhancing agents for the treatment of type 2 diabetes mellitus; in mid-2008, BEOV advanced to phase 11 clinical testing. The interactions of BMOV and its inorganic congener, vanadyl Sulfate (VOSO4), with human serum apo-transferrin (hTf) were investigated using differential scanning calorimetry (DSC). Addition of BMOV or VOSO4 to apo-hTf resulted in an increase in thermal stability of both the C- and N-lobes of transferrin as a result of binding to either vanadyl compound. A series of DSC thermograms of hTf Solutions containing different molar ratios of BMOV and VOSO4 were used to determine binding constants: at 25 degrees C the binding constants of BMOV to the C- and N-lobes of apo-hTf were found to be 3 (+/- 1) x 10(5) and 1.8 (+/- 0.7) x 10(5) M-1, respectively. The cot-responding values for VOSO4 were 1.7 (+/- 0.3) x 10(5) and 7 (+/- 2) x 10(4) M-1. The results show that the vanadium species initially presented as either BMOV or VOSO4 had similar affinities for human serum transferrin due to oxidation of solvated vanadyl(IV) prior to complexation to transferrin. Binding of metavanadate (VO3-) was confirmed by DSC and isothermal titration calorimetry (ITC) experiments of the interaction between sodium metavanadate (NaVO3) and hTf. (C) 2008 Elsevier Inc.

Dysfunctional interactions of metal ions, especially those of Cu, Zn, and Fe, with the amyloid-beta (A beta) peptide are hypothesised to play an important role in the aetiology of AD, and disruption of these aberrant metal-peptide interactions via chelation therapy holds considerable promise as a therapeutic strategy. Tetrahydrosalens such as H2L1-5 have a significant affinity for metal ions, and thus should be able to compete with the A beta peptide for Cu, Zn, and Fe in the brain. This activity was assayed in vitro via a turbidity assay; H2L1 and H2L3 were found to attenuate A beta(1-40) aggregation after exposure to Cu2+ and Zn2+. In addition, H2L1-5 were determined to be potent antioxidants on the basis of an in vitro antioxidant assay. GL(1-5) were prepared as metal binding prodrugs; glycosylation is intended to prevent systemic metal binding, improve solubility, and enhance brain uptake. Enzymatic (beta-glucosidase) deprotection of the carbohydrate moieties was facile, with the exception of GL(4), demonstrating the general feasibility of this prodrug approach. Finally, a representative prodrug, GL(3), was determined to be non-toxic over a large concentration range in a cell viability assay.},

This hydride undergoes a rapid reaction with ethylene to generate a nickel(O) complex in which an ethyl group has been transferred to the carbene carbon of the original NHC-diphosphine ligand. If the first intermediate is the anticipated square-planar nickel(II) ethyl species, then the formation of the product would require a process that involves a trans C-C coupling of the NHC carbon and a presumed Ni-ethyl intermediate. Deuterium-labeling studies provide evidence for migratory insertion of the added ethylene into the Ni-H bond rather than into the Ni-catene linkage; this is based on the observed deuterium scrambling, which requires reversible P-elimination, alkene rotation, and hydride readdition. However, density functional theory studies suggest that a key intermediate is an agostic ethyl species that has the Ni-C bond cis to the NHC unit. A possible transition state containing two cis-disposed carbon moieties was also identified. Such a process represents a new pathway for catalyst deactivation involving NHC-based metal complexes.},

	abstract = {Proteins are the true workhorses of any cell. To carry out specific tasks, they frequently bind other molecules in their surroundings. Due to their structural complexity and flexibility, the most diverse array of interactions is seen with other proteins. The different geometries and affinities available for such interactions typically bestow specific functions on proteins. Having available a map of protein - protein interactions is therefore of enormous importance for any researcher interested in gaining insight into biological systems at the level of cells and organisms. In a recent report, a novel approach has been employed that relies on the spontaneous folding of complementary enzyme fragments fused to two different proteins to test whether these interact in their actual cellular context [Tarassov et al., Science 320, 1465-1470 (2008)]. Genome- wide application of this protein- fragment complementation assay has resulted in the first map of the in vivo interactome of Saccharomyces cerevisiae. The current data show striking similarities but also significant differences to those obtained using other large- scale approaches for the same task. This warrants a general discussion of the current state of affairs of protein - protein interaction studies and foreseeable future trends, highlighting their significance for a variety of applications and their potential to revolutionize our understanding of the architecture and dynamics of biological systems.},

	abstract = {Formaldehyde cross-linking of proteins is emerging as a novel approach to study protein-protein interactions in living cells. It has been shown to be compatible with standard techniques used in functional proteomics such as affinity-based protein enrichment, enzymatic digestion, and mass spectrometric protein identification. So far, the lack of knowledge on formaldehyde-induced protein modifications and suitable mass spectrometric methods for their targeted detection has impeded the identification of the different types of crosslinked peptides in these samples. In particular, it has remained unclear whether in vitro studies that identified a multitude of amino acid residues reacting with formaldehyde over the course of several days are suitable substitutes for the much shorter reaction times of 10-20 min used in cross-linking experiments in living cells. The current study on model peptides identifies amino-termini as well as lysine, tryptophan, and cysteine side chains, i.e. a small subset of those modified after several days, as the major reactive sites under such conditions, and suggests relative position in the peptide sequence as well as sequence microenvironment to be important factors that govern reactivity. Using MALDI-MS, mass increases of 12 Da on amino groups and 30 Da on cysteines were detected as the major reaction products, while peptide fragment ion analysis by tandem mass spectrometry was used to localize the actual modification sites on a peptide. Non-specific cross-linking was absent, and could only be detected with low yield at elevated peptide concentrations. The detailed knowledge on the constraints and products of the formaldehyde reaction with peptides after short incubation times presented in this study is expected to facilitate the targeted mass spectrometric analysis of proteins after in vivo formaldehyde cross-linking.

These molybdenacyclobutane complexes do not react via olefin metathesis or cyclopropanation pathways, but instead via C-H activation. Thus, when cyclopentene is the olefinic substrate, the direct result of C-H activation at the beta-position of the metallacyclobutane affords a thermally stable allyl hydrido complex that can be isolated. Such an allyl hydride intermediate is not isolable for larger cyclic olefins (cyclohexene, cycloheptene, and cyclooctene) or acyclic olefins (allylbenzene and 1-hexene). Instead, those complexes react further, undergoing a second C-H activation at the allylic position to produce eta(4)-trans-diene complexes concomitant with the loss of dihydrogen. Upon heating, these eta(4)-trans-diene complexes liberate diene, thereby enabling the 14e Cp*Mo(NO) metal fragment to catalyze the oligomerization of cyclic olefins and dienes including cyclohexene and 1,4-cyclohexadiene. In the case of the acyclic olefin allylbenzene, the metal fragment catalyzes a dimerization to (E)-(4-methylpent-1-ene-1,5-diyl)dibenzene under ambient conditions.},

	abstract = {For decades, formaldehyde has been routinely used to cross-link proteins in cells, tissue, and in some instances, even entire organisms. Due to its small size, formaldehyde can readily permeate cell walls and membranes, resulting in efficient cross-linking, i.e. the formation of covalent bonds between proteins, DNA, and other reactive molecules. Indeed, formaldehyde cross-linking is an instrumental component of many mainstream analytical/cell biology techniques including chromatin immunoprecipitation (ChIP) of protein-DNA complexes found in nuclei; immunohistological analysis of protein expression and localization within cells, tissues, and organs; and mass spectrometry (MS)-compatible silver-staining methodologies used to visualize low abundance proteins in polyacrylamide gels. However, despite its exquisite suitability for use in the analysis of protein environments within cells, formaldehyde has yet to be commonly employed in the directed analysis of protein-protein interactions and cellular networks. The general purpose of this article is to discuss recent advancements in the use of formaldehyde cross-linking in combination with MS-based methodologies. Key advantages and limitations to the use of formaldehyde over other cross-linkers and technologies currently used to study protein-protein interactions are highlighted, and formaldehyde-based experimental approaches that are proving very promising in their ability to accurately and efficiently identify novel protein-protein and multiprotein interaction complexes are presented.

Cytotoxicity of these polymers is significantly lower than that of PEI and is a function of quarternized nitrogen present in the polymer. Also, these polymers bind DNA in the nanomolar range and are able to condense DNA to highly compact, stable, water soluble nanoparticles in the range of 60-80 nm. Gel electrophoresis studies showed that they form electroneutral complexes with DNA around N/P ratio 1 irrespective of the percentage of quarternization under the conditions studied.

Ligands that adequately bind metal ions and also include specific targeting features are gaining in popularity due to their ability to enhance the efficacy of less complicated metal-based agents. Moving beyond the traditional view of ligands modifying reactivity, stabilizing specific oxidation states, and contributing to substitution inertness, we will discuss recent work involving metal complexes with multifunctional ligands that target specific tissues, membrane receptors, or endogenous molecules, including enzymes.},

With the peaks in the Si-29 spectrum assigned to the inequivalent Si sites in the zeolite from a two-dimensional INADEQUATE spectrum, the rates of cross polarization between the H-1 nuclei of the guest sorbate molecules and the Si-29 nuclei of the zeolite framework were used to determine the location of the naphthalene molecules by exploiting the proportional relationship between cross-polarization rate constants and H-1/Si-29 dipolar coupling second moments. The NMR structure determination was carried out on three different selectively deuterium-labeled naphthalene molecules (naphthalene-d(0), alpha-naphthalene-d(4), and beta-naphthalene-d(4)). The average of the molecule locations in agreement with all three sets of NMR data was found to be in excellent agreement with an existing single crystal XRD structure of the naphthalene-ZSM-5 complex.},

	abstract = {The fine and hyperfine interaction parameters in the [18.8] (3)Phi (upsilon=0) and X (3)Phi (upsilon=0) states of cobalt monofluoride, CoF, have been determined from an analysis of high-resolution laser induced fluorescence spectra of the [18.8] (3)Phi(3)-X (3)Phi(3) and [18.8] (3)Phi(4)-X (3)Phi(4) band systems. The previously reported pure rotational transitions of the X (3)Phi(4)(upsilon=0) state [T. Okabayashi and M. Tanimoto, J. Mol. Spectrosc. 221, 149 (2003)] were included in the data set. The hyperfine parameters for Co-59 (I=7/2) and F-19 (I=1/2) have been interpreted using atomic data together with a proposed molecular orbital description for the [18.8](3)Phi(i) and X (3)Phi(i) states. A comparison of the hyperfine parameters in the X (3)Phi state of cobalt monohydride, CoH, with those of the X (3)Phi state of CoF reveals that the bonding in the two molecules is significantly different. It is shown that, in a situation where the Omega substates of a multiplet degenerate electronic state are analyzed separately, the Fermi contact parameter b can be determined with fair accuracy from the apparent centrifugal distortion of the hyperfine structure.

	abstract = {Activation of molecular nitrogen by transition metal complexes is an area of current interest as investigations using the inert N-2 molecule to produce higher-value organonitrogen compounds intensify. In an attempt to extend the addition of hydride reagents E-H (where E = BR2, AIR(2), and SiR3) to the dinitrogen complex ([NPN]Ta)(2)(mu-H)(2)(mu-eta(2):eta(2)-N-2) [1; where NPN = (PhNSiMe2CH2)(2)PPh], the reaction with zirconocene chlorohydride, [Cp2Zr(Cl)H](x), was examined. The crystalline product formed in 35\% yield was determined to be ([NP(N)N]Ta)(mu-H)(2)(mu-N)(Ta[NPN])(ZrCP2) (2) in which the coordinated N-2 has been cleaved to form a phosphinimide bridging between Ta and Zr and a triply bridging nitride. The mechanism of this reaction was examined to determine the fate of the chloride and hydricle ligands attached to Zr in the starting zirconocene reagent. Using the zirconocene dihydride dimer ([Cp2ZrH2](2)), a higher yield of 2 was obtained (76\%), and H-2 was also observed by H-1 NMR spectroscopy. To probe the origin of the eliminated H-2, the dideuterated dinitrogen complex ([NPN]Ta)(2)(tLID)(2)(mu-eta(1):n(2)-N-2) (d(2)-1) was allowed to react with ([CP2ZrH2](2)), which resulted in the formation of ([NP(N)N]Ta)(mu-D)(2)(mu-N)(Ta[NPN]) (ZrCP2), (d(2)-2), with no evidence of hydrogen for deuterium scrambling between the starting zirconocene dihydride and the ditantalum dinitrogen complex. Studies into the use of preformed Zr(II) and Ti(II) reagents were also performed. The proposed mechanism involves initial adduct formation that facilitates inner-sphere electron transfer to cleave the N-N bond to form a species with bridging nitrides, one of which is transformed by nucleophilic attack of a phosphine donor to generate the observed phosphinimide.},

The X-ray structure of E-propophenone semicarbazone is also reported. Rhodium-catalyzed, homogeneous hydrogenation of semicarbazones was not observed even at 40 atm H-2.},

	abstract = {Significant new insights into the interactions of the potent insulin-enhancing compound bis(maltolato)oxovanadium(IV) (BMOV) with the serum proteins, apo-transferrin and albumin, are presented. Identical reaction products are observed by electron paramagnetic resonance (EPR) with either BMOV or vanadyl sulfate (VOSO4) in solutions of human serum apo-transferrin. Further detailed study rules out the presence of a ternary ligand-vanadyl-transferrin complex proposed previously. By contrast, differences in reaction products are observed for the interactions of BMOV and VOSO4 with human serum albumin (HSA), wherein adduct formation between albumin and BMOV is detected. In BMOV-albumin solutions, vanadyl ions are bound in a unique manner not observed in comparable solutions Of VOSO4 and albumin. Presentation of chelated vanadyl ions precludes binding at the numerous nonspecific sites and produces a unique EPR spectrum which is assigned to a BMOV-HSA adduct. The adduct species cannot be produced, however, from a solution Of VOSO4 and HSA titrated with maltol. Addition of maltol to a VOSO4-HSA solution instead results in formation of a different end product which has been assigned as a ternary complex, VO(ma)(HSA). Furthermore, analysis of solution equilibria using a model system of BMOV with 1-methylimidazole (formation constant log K = 4.5(1), by difference electronic absorption spectroscopy) lends support to an adduct binding mode (VO(ma)(2)-HSA) proposed herein for BMOV and HSA. This detailed report of an in vitro reactivity difference between VOSO4 and BMOV may have bearing on the form of active vanadium metabolites delivered to target tissues. Albumin binding of vanadium chelates is seen to have a potentially dramatic effect on pharmacokinetics, transport, and efficacy of these antidiabetic chelates.},

The conformational changes of the porphyrinic macrocycle during the course of this degradation, as determined by comparison of the X-ray crystal structures of the compounds, are discussed.

These complexes maintain their integrity in acetone solution and show no reaction toward 1 atm H-2 at ambient conditions. In MeOH, the complexes in which R {\textquoteright} = Me simply change to the corresponding MeOH derivative, but when R {\textquoteright} = H they are partially converted to the non-orthometalated, eta(1)-N-imine species [Rh(PPh3)(2)(RN=CHR {\textquoteright}{\textquoteright})(MeOH)]PF6 (I), and in MeOH, stoichiometric hydrogenation of the imine to the corresponding amine occurs via I. We have shown recently (Inorg. Chem. 2004, 43, 4820) that the catalyzed hydrogenation of PhCH2N=C(H)Ph to dibenzylamine using cis, trans, cis- [Rh(H)(2)(PPh3)(2)(MeOH)(2)] PF6 as catalyst precursor in MeOH proceeds via a cationic Rh-(eta(1)-N-imine)(amine) intermediate (II), analogous to I but with the MeOH replaced by the amine that is formed via hydrolysis of the imine by the presence of adventitious water. Intermediate I (R = PhCH2, R {\textquoteright}{\textquoteright} = Ph) is shown to be somewhat less active than II toward H-2, but both intermediates provide viable pathways for hydrogenation of the imine. The orthometalated imine-amine complex [Rh(H){PhCH2N=C(Me)(o-C6H4)}(PPh3)(2)(NH2CH2Ph)]PF6, where the benzylamine comes from imine hydrolysis, is also isolated and characterized crystallographically.},

Analysis of the spectra indicates that (i) both chemical systems are unusually strongly bound compared to conventional van der Waals complexes, (ii) significant charge rearrangement occurs at the xenon nucleus upon formation of both XeAgF and XeAgCl as shown by the Xe-131 nuclear quadrupole coupling constants and (iii) in both XeAgF and XeAgCl the Xe-Ag distance is small compared to the sum of the Xe van der Waals radius and the Ag+ ionic radius. An ab initio study of the two species has been performed. The combined experimental and theoretical investigations indicate that the Xe-Ag interaction is not easily described, but that there is some evidence for weak chemical bonding.},

The cations with metals in oxidation states of +2 or +3 are termed "superelectrophilic".

	abstract = {beta-Trifluoromethyl-meso-tetraphenylporphyrins were synthesized to investigate the electronic and steric effects of the trifluoromethyl groups on the macrocycle. Preparation of these novel porphyrins was carried out by copper-assisted trifluoromethylation of beta-tetrabromo-meso-tetraphenylporphyrin metal complexes and in situ generated CF3Cu. For comparison, the beta-methyl analogues were also prepared. Analysis of beta-trifluoromethylporphyrins by UV-vis, NMR, and cyclic voltammetry (CV) showed that the electron-withdrawing effects of the trifluoromethyl groups on the antipodal pyrroles required the macrocycle to take a fixed 18pi-electron pathway. UV-vis, CV, and molecular modeling studies suggest that the novel porphyrins are distorted following introduction of trifluoromethyl groups onto the pyrrolic beta-position of meso-tetraphenylporphyrin. The pK(a) difference of beta-tetrakis(trifluoromethyl)-meso-tetraphenylporphyrin from that of DBU in CH2Cl2, obtained by spectrophotometric titration, affirms that it is one of the most electron-deficient porphyrins so far prepared.},

	abstract = {Gentle thermolysis of the allyl complex, (CpW)-W-*(NO)(CH2CMe3)(eta(3)-H2CCHCMe2) (1), at 50 degreesC in neat hydrocarbon solutions results in the loss of neopentane and the generation of transient intermediates that subsequently activate solvent C-H bonds. Thus, thermal reactions of 1 with tetramethylsilane, mesitylene, and benzene effect single C-H activations and lead to the exclusive formation of (CpW)-W-*(NO)(CH2SiMe3)(eta(3)-H2CCHCMe2) (2), (CpW)-W-*(NO)(CH2C6H3-3,5-Me-2)(eta(3)-H2CCHCMe2) (3), and (CpW)-W-*(NO)(C6H5)(eta(3)-H2CCHCMe2) (4), respectively. The products of reactions of 1 with other methyl-substituted arenes indicate an inherent preference of the system for the activation of stronger arene sp(2) C-H bonds. For example, C-H bond activation of p-xylene leads to the formation of (CpW)-W-*(NO)(CH2C6H4-4-Me)(eta(3)-H2CCHCMe2) (5) (26\%) and (CpW)-W-*(NO)(C6H3-2,5-Me-2)(eta(3)-H2CCHCMe2) (6) (74\%). Mechanistic and labeling studies indicate that the transient C-H-activating intermediates are the allene complex, (CpW)-W-*(NO)(eta(2)-H2C=C=CMe2) (A), and the eta(2)-diene complex, (CpW)-W-*(NO)(eta(2)-H2C=CHC(Me)=CH2) (B). Intermediates A and B react with cyclohexene to form (CpW)-W-*(NO)(eta(3)-CH2C(2-cyclohexenyl)CMe2)(H) (18) and (CpW)-W-*(NO)(eta(3)-CH2CHC)(Me)CH2CbetaH(C4H8)CalphaH (19), respectively, and intermediate A can be isolated as its PMe3 adduct, (CpW)-W-*(NO)(PMe3)(eta(2)-H2C=C=CMe2) (20). Interestingly, thermal reaction of 1 with 2,3-dimethylbut-2-ene results in the formation of a species that undergoes eta(3) {\textendash}> eta(1) isomerization of the dimethylallyl ligand following the initial C-H bond-activating step to yield (CpW)-W-*(NO)(eta(3)-CMe2CMeCH2)(eta(1)-CH2CHCMe2) (21). Thermolyses of 1 in alkane solvents afford allyl hydride complexes resulting from three successive C-H bond-activation reactions. For instance, 1 in cyclohexane converts to (CpW)-W-*(NO)(eta(3)-C6H9)(H) (22) with dimethylpropylcyclohexane being formed as a byproduct, and in methylcyclohexane it forms the two isomeric complexes, (CpW)-W-*(NO)(eta(3)-C7H11)(H) (23a,b). All new complexes have been characterized by conventional spectroscopic methods, and the solid-state molecular structures of 2, 3, 4, 18, 19, 20, and 21 have been established by X-ray crystallographic analyses.},

From this set of ligand precursors, air-stable VO(L-1)(2), VO(L-3)(2), and VO(L-4)(2) were prepared. The four ligand precursors and three complexes were tested for insulin-enhancing potential in STZ-diabetic rats and compared to rosiglitazone and BMOV, respectively. Both the ligand precursors HL1 and HL3 showed enhanced activity compared with that of rosiglitazone. The complex VO(L-3)(2) showed the most efficacious hypoglycemic effects in this study; however, neither additive nor synergistic effects were observed using this acute animal model.},

	abstract = {An X-ray diffraction study on syn-Pd2Cl2(dppmMe)(2), syn-1, shows an unusual boat-like conformation of the eight-membered Pd2P4C2 ring. This conformation, containing equatorial Me groups, facilitates access of the Pd-Pd bond to small molecules such as CO, SO2, and elemental sulfur or selenium, and makes the syn isomer more reactive than anti-1. A comparison of bond angles around the Pd and P atoms in the syn- and anti-isomers reveals a more strained geometry of the former, which may also contribute to the stronger propensity of syn-1 to form A-frame adducts. Solution NMR/NOE studies on syn- and anti-1 and their (mu-Se) adducts reveal the structural rigidity of these complexes; the Me groups inhibit the interchange of axial and equatorial positions on the bridging methine C-atom, and solution structures correspond to those in the solid state. The X-ray structure of Pd2Cl2(dppm)(2) is, as expected, like that of the corresponding bromo, complex; both are analogous to that of anti-1 which adopts a chair conformation within both the fused, five-membered rings.

The cyclobutanols readily undergo retro-aldol reaction to give delta-ketoesters. The enantiomeric excess (ee) in the endo-cyclobutanols is measured by monitoring the ee in the ketoesters. Whereas in solution the ee in the product ketoester is zero, within achiral NaY zeolite, in the presence of a chiral inductor such as pseudoephedrine, ee{\textquoteright}s up to 28\% have been obtained. The influence of zeolite on several chiral esters of 2-benzoyladamantane-2-carboxylic acids has also been examined. Whereas in solution the diastereomeric excess is <15\%, in zeolite the delta-ketoesters are obtained in 79\% de (best examples). Ab initio computations suggest that enhancement of chiral induction within zeolites is likely to be due to cation complexation with the reactant ketone. Alkali ion-organic interaction, a powerful tool, is waiting to be fully exploited in photochemical and thermal reactions. In this context zeolites could be a useful medium as one could view them as a reservoir of "naked" alkali ions that are only partially coordinated to the zeolite walls.},

Previously, tissue uptake of vanadium from bis(maltolato)oxovanadium(IV) (BMOV) was shown to be increased compared to its uptake from vanadyl sulfate (VS). Our primary objective was to test the hypothesis that complexation increases vanadium uptake and that this effect is independent of oxidation state. A secondary objective was to compare the effects of vanadium complexation and oxidation state on tissue iron, copper, and zinc. Wistar rats were fed either ammonium metavanadate (AMV), VS, or BMOV (1.2 mM each in the drinking water). Tissue uptake of V following 12 wk of BMOV or AMV was higher than that from VS (p < 0.05). BMOV led to decreased tissue Zn and increased bone Fe content. The same three compounds were compared in a cellular model of absorption (Caco-2 cells). Vanadium uptake from VS was higher than that from BMOV or AMV at 10 min, but from BMOV (250 \&mu;M only, 60 min), uptake was far greater than from AMV or VS. These results show that neither complexation nor oxidation state alone are adequate predictors of relative absorption, tissue accumulation, or trace element interactions.},

All three molecules are linear, Accurately determined rotational constants have been used to evaluate the various internuclear distances, which are found to be consistent with trends established for OCAuX and OCCuX species. The C-O distances are short, and the M-C distances are significantly longer than those in other molecules containing a metal-carbonyl bond, Precise values of centrifugal distortion constants and halogen nuclear quadrupole coupling constants have also been determined. The coupling constants are compared with the results of previous studies of OCCuX and OCAuX and are used to infer trends in the electron distributions of the molecules.

	abstract = {Tris(trifluoromethyl)borane carbonyl, (CF3)(3)BCO, is obtained in high yield by the solvolysis of K[B(CF3)(4)] in concentrated sulfuric acid. The in situ hydrolysis of a single bonded CF3 group is found to be a simple, unprecedented route to a new borane carbonyl. The related, thermally unstable borane carbonyl, (C6F5)(3)BCO, is synthesized for comparison purposes by the isolation of (C6F5)(3)B in a matrix of solid CO at 16 K and subsequent evaporation of excess CO at 40 K. The colorless liquid and vapor of (CF3)3BCO decomposes slowly at room temperature. In the gas phase t(1/2) is found to be 45 min. In the presence of a large excess of (CO)-C-13, the carbonyl substituent at boron undergoes exchange, which follows a first-order rate law. Its temperature dependence yields an activation energy (EA) of 112 kJ mol(-1). Low-pressure flash thermolysis of (CF3)3BCO with subsequent isolation of the products in low-temperature matrixes, indicates a lower thermal stability of the (CF3)3B fragment, than is found for (CF3)3BCO. Toward nucleophiles (CF3)3BCO reacts in two different ways: Depending on the nucleophilicity of the reagent and the stability of the adducts formed, nucleophilic substitution of CO or nucleophilic addition to the C atom of the carbonyl group are observed. A number of examples for both reaction types are presented in an overview. The molecular structure of (CF3)(3)BCO in the gas phase is obtained by a combined microwave-electron diffraction analysis and in the solid state by single-crystal X-ray diffraction. The molecule possesses C3 symmetry, since the three CF3 groups are rotated off the two possible positions required for C3, symmetry. All bond parameters, determined in the gas phase or in the solid state, are within their standard deviations in fair agreement, except for internuclear distances most noticeably the B-CO bond lengths, which is 1.69(2) Angstrom in the solid state and 1.617(12) Angstrom in the gas phase. A corresponding shift of nu(CO) from 2267 cm(-1) in the solid state to 2251 cm-1 in the gas phase is noted in the vibrational spectra. The structural and vibrational study is supported by DFT calculations, which provide, in addition to the equilibrium structure, confirmation of experimental vibrational wavenumbers, IR-band intensities, atomic charge distribution, the dipole moment, the B-CO bond energy, and energies for the elimination of CF2 from (CF3)(x)BF3-x1 = 1-3. In the vibrational analysis 21 of the expected 26 fundamentals are observed experimentally. The B-11-, C-13-, and F-19-NMR data, as well as the structural parameters of (CF3)(3)BCO, are compared with those of related compounds.},

	abstract = {The solid-state molecular structure of Cp*W(NO)(CH2CMe3)(2) (1) has been shown to contain one "strongly agostic" and one "weakly agostic" methylene hydrogen atom by a neutron diffraction analysis at 120 K and by an X-ray diffraction analysis at -100 degreesC. The X-ray diffraction analysis of Cp*W(NO)(CH2SiMe3)(2) (2) at -20 degreesC reveals that its solid-state molecular structure possesses a crystallographically imposed mirror plane. Consequently, only the average existence of a relatively strong C-(HM)-M-... interaction for each hydrocarbyl ligand in 2 in the solid state can be established. The H-1 and gated C-13{H-1} NMR spectra of representative Cp{\textquoteright}M(NO)(R)(R{\textquoteright}) (M = Mo, W; R = hydrocarbyl, R{\textquoteright} = hydrocarbyl, halide, amide) complexes exhibit spectral parameters for the alpha -H and alpha -C atoms (i.e., delta (H), delta (C), Delta delta (H), DeltaJ(HC), and J(HW)) that provide evidence for the presence of a-agostic interactions in the molecular structures of these complexes in solution. The picture that has emerged from these investigations is that these complexes do adopt an a-agostic structure both in solution and in the solid state when secondary interactions such as pi -electron donation are weak (as in Cp*W(NO)(CH2CMe3)Cl), competitive (as in Cp*W(NO)(CH2CMe3)(CH2Ph)), or not possible (as in Cp*W(NO)(hydrocarbyl)(2) complexes generally). The bis(hydrocarbyl) complexes are probably stereochemically nonrigid in solution, as they appear to interconvert between the two limiting structures having one strongly agostic and one weakly agostic hydrocarbyl ligand. The neopentyl ligand forms alpha -agostic linkages with the metal centers in all neopentyl complexes studied, and these agostic interactions appear to be independent of the nature of the metal or the ancillary cyclopentadienyl ligand. Interestingly, the presence of these groundstate agostic interactions does not correlate with the tendency of the various compounds to undergo intramolecular alpha -H abstraction reactions and form reactive alkylidene complexes.},

The starting materials, {[P2N2]M}(2)(mu -Cl)(2), (M = Y, Sm, Ho, Yb, Lu), are prepared by the reaction of syn-Li-2(dioxane)[P2N2] with MCl3(THF)(3) in toluene. The reactivity of these complexes toward PhLi and other arylating agents is dependent on the size of the M3+ ion. M = Y and Ho undergo C-C bond formation reactions to give biphenyldiide compounds {[P2N2]M}(2){mu-eta (6):eta (6 {\textquoteright})-(C6H5)(2)} and {[P2N2]Y}(2){mu-eta (6):eta (6 {\textquoteright})-(C6H4-p-Ph)(2)} These have been structurally characterized and show the biphenyl dianion bridging two [P2N2]M fragments. These [P2N2]M fragments migrate over the bridging ligand{\textquoteright}s pi -surface on the NMR time scale. M = Yb yields the paramagnetic monophenyl derivative [P2N2]Yb-(C6H5), where the Yb center is coordinatively unsaturated and resides in a distorted square-pyramidal environment. M = Lu results in a mixture of "ate" complexes of the formulation "[P2N2]LuPh . LiCl", as evidenced by Li-7 NMR. However, the biphenyl product {[P2N2]Lu}(2)-{mu-eta (6):eta (6 {\textquoteright})-(C6H5)(2)} can be synthesized via a reductive route. The presence of THF was found to be deleterious to the coupling reaction; in this case, the THF adduct [P2N2]Y(C6H4-p-Me)-(THF) was isolated and structurally characterized. The mechanism for the C-C bond formation reaction is described based on the isolation of these yttrium and lanthanide complexes.},

[Co-II(XT)](3-), [Co-III(XT)](2-), and a series of [Ln(XT)](2-) complexes have been prepared. The phosphinate group is not coordinated in the Co complexes but is bound in the lanthanide complexes. Solid state and solution behaviors of Ln-XT species are consistent: both monoprotonated and nonprotonated species have been found. Protonation of the metal complex does not lead to dissociation of a carboxylate; rather, the proton distributes around the molecular ion. The pM values of Ln-XT are comparable to those of Ln-EDTA but are higher than those of Ln-TMDTA. The inclusion of a phosphinate eases the selectivity of an EDTA-type ligand for late lanthanides.},

	abstract = {A pulsed jet cavity Fourier transform microwave spectrometer has been used to measure the rotational spectra of OCCuX (X = F, Cl, Br) in the frequency range 5-21 GHz. Metal atoms were generated via laser ablation and were allowed to react with CO and a halide precursor, prior to stabilization of the products within a supersonic jet. These are the first experimental observations of OCCuF and OCCuBr and the first high-resolution spectroscopic study of gas-phase OCCuCl. All three molecules were found to be linear. Rotational constants, centrifugal distortion constants, nuclear quadrupole coupling constants, and nuclear spin-rotation coupling constants have been precisely determined. The rotational constants have been used to evaluate the various bond lengths, and the results are in good agreement with the trend established for OCAuX species. The C-O distance is found to be comparatively short and close to that of free CO. The M-C distance is longer than that predicted by ab initio calculations, and the Cu-X distances are very similar to those observed in the corresponding metal halides. Vibrational wavenumbers have been estimated from the distortion constants and are compared with the results of various ab initio studies. Changes in the Cu, Cl, and Br nuclear quadrupole coupling constants indicate that substantial charge rearrangement takes place on coordination with CO, consistent with the formation of strong Cu-C bonds. Mulliken orbital population analyses have been performed and provide evidence of pi -back-donation from Cu in all of the species studied. The evaluated nuclear spin-rotation coupling constants have been used to estimate the Cu-63 nuclear shielding constants, sigma, and their spans (Omega) in (OCCuF)-Cu-63, (OCCuCl)-Cu-63-Cl-35, and (OCCuBr)-Cu-63-Br-79.},

The complex was found to be linear and relatively rigid, with a Kr-Ag bond length of similar to2.641 Angstrom. The Kr-Ag stretching frequency was estimated to be 117 cm(-1). Ab initio calculations performed at the MP2 level of theory gave the geometry, vibration frequencies, Kr-Ag bond dissociation energy, and orbital populations. The Kr-Ag bond dissociation energy was estimated to be -28 kJ mol(-1). The Kr-Ag force constant and dissociation energy are greater than those of Ar-Ag in Ar-AgCl. The chlorine nuclear quadrupole coupling constants show slight changes on complex formation. Ab initio orbital population analysis shows a small shift in sigma -electron density from Kr to Ag on complex formation. The combined experimental and ab initio results are consistent with the presence of a weak Kr-Ag covalent bond. (C) 2001 Academic Press},

A mechanistic study suggests that the formation of [P2N2]Ta(C2H4)Et results from the trapping of [P2N2]TaEt, formed by the migratory insertion of the methylene moiety into the tantalum-methyl bond. The minor product, [P2N2]Ta(C2H4)Me, forms from the decomposition of a tantalacyclobutane resulting from the addition of ethylene to [P2N2]Ta=CH2(Me) and is accompanied by the production of an equivalent of propylene. Pure [P2N2]Ta(C2H4)Et can be synthesized by hydrogenation of [P2N2]TaMe3 in the presence of PMe3, followed by the reaction bf ethylene with the resulting trihydride. Crystallographic and NMR data indicate the presence of a beta -agostic interaction between the ethyl group and tantalum center in [P2N2]Ta(C2H4)Et. Partially deuterated analogues of [P2N2]Ta(C2H4)Et show a large isotopic perturbation of resonance for both the beta -protons and the alpha -protons of the ethyl group, indicative of an equilibrium between a beta -agostic and an a-agostic interaction for the ethyl group in solution. An EXSY spectrum demonstrates that an additional fluxional process occurs that exchanges all of the H-1 environments of the ethyl and ethylene ligands. The mechanism of this exchange is believed to involve the direct transfer of the beta -agostic hydrogen atom from the ethyl group to the ethylene ligand, via the so-called beta -hydrogen transfer process.},

	abstract = {The utility of electrospray ionization mass spectrometry (ESI-MS) for characterizing dissolved metal species has generated considerable interest in the use of this technique for metal speciation, However, the development of accurate speciation methods based on ESI-R;IS requires a detailed understanding of the mechanisms by which dissolved metal species are ionized during electrospray. We report how the analysis of alkali and alkaline earth metal species pro,ides new information about some of the processes that affect electrospray ion yield. Selected metal ions and organic ligands were combined in 50:50 water-acetonitrile buffered with acetic acid or ammonium acetate and analyzed by flow injection ESI-MS using mild electrospray conditions. Species formed by alkali metal ions with thiol and oxygen-donating ligands were detected in acidic and neutral pH solutions. Electrochemical oxidation of N,N-diethyldithiocarbamate and glutathione during electrospray was indicated by detection of the corresponding disulfides as protonated or alkali metal species, The extent of ligand oxidation depended on solution pH and the dissociation constant of the thiol group, Tandem mass spectrometric experiments suggested that radical cations such as [NaL](+.) (where L = N,N -diethyldithiocarbamate) can be generated by in-source fragmentation of disulfide species. Greater complexation of alkali metals at neutral pH tvas indicated by a corresponding decrease in the relative abundance of the free metal ion, The number of alkali metal ions bound by glutathione and phthalic acid also increased with increasing pH, in accordance with thermodynamic equilibrium theory. Alkaline earth metal species were detected only in acidic solutions, the absence of 8-hydroxyquinoline complexes being attributed to their relative instability and subsequent dissociation during electrospray, Hence, accurate speciation by ESI-MS depends on experimental conditions and the intrinsic properties of each analyte, Copyright (C) 2000 John Wiley \&; Sons, Ltd.},

Isotopic data have been used to calculate an r(0) structure for Ar-CuF, while for Ar-CuCl and Ar-CuBr partial substitution structures have also been obtained. To reduce zero-point vibrational effects a double substitution method (r(d)) has also been employed to calculate the structures of Ar-CuCl and Ar-CuBr.

Under 4 atm of hydrogen gas, further hydrogenation does not produce the complex [P2N2]TaH3; instead, reduction of the tantalum center occurs to yield the dinuclear Ta(IV) hydride ([P2N2]Ta)(2)-(mu-H)(4). This diamagnetic tetrahydride fails to react with many reagents, including ethylene and carbon monoxide; however, upon addition of iodomethane, {([P2N2]Ta)(2)(mu-H)(4)}I-+(-) is produced as a paramagnetic green crystalline solid. The number of hydrides in this reaction product was confirmed by a deuterium labeling study. The results of a variable-temperature magnetic susceptibility study of this tetrahydride cation can be partially modeled with the Curie-Weiss law and a large correction for temperature-independent magnetism. Ab initio calculations using density functional theory were performed in an attempt to further understand the influence of the macrocyclic ligand in the bonding in these complexes.},

	abstract = {Hexakis/carbonyl iron(LI) undecafluorodiantimonate(V), [Fe(CO)(6)][Sb2F11](2) is conveniently prepared by the oxidative carbonylation of Fe(CO)(5) with XeF2 as external oxidizer in the conjugate Br phi nsted-Lewis superacid HF-SbF5. The colorless compound crystallizes from the reaction medium in high purity. The molecular structure is obtained by single-crystal X-ray diffraction. The cation is a regular octahedron, while the vertex-shared di-octahedral [Sb2F11](-) anion is distorted from D-4h symmetry by bending and rotational processes, due to significant interionic interactions, primarily of the FC type. Washing of [Fe(CO)(6)][Sb2F11](2) with anhydrous HF results in an unusual elution of SbF5 and the quantitative conversion to hexakis(carbonyl)iron(II) hexafluoroantimonate;(V) [Fe(CO)(6)][SbF6](2) The molecular structure of the salt shows octahedral ions with slight tetragonal distortions for the cation (elongation) and the anion (comprsssion). Both salts are thermally stable up to 150 degrees C, The averaged bond distances and the vibrational wavenumbers of [Fe(CO)(6)](2+) are nearly identical in both compounds. The [Fe(CO)(6)](2+) cation, the first and so far only isolated and structurally characterized dipositive, superelectrophilic carbonyl cation formed by a 3d-metal, is further characterized by a normal coordinate analysis (NCA). The obtained force constants are compared to those of the isoelectronic molecule Cr(CO)6. Changes in pi-back-bonding affect the F-CO/CO and F-CO/MC interaction force constants more strongly than the stretching force constants F-CO and F-MC All 13 fundamentals of [Fe(CO)(6)](2+) are detected and assigned with the help of the data obtained from the normal coordinate analysis and density functional calculations published previously. The electronic ground state (1)A(1g), of the [Fe(CO)(6)](2+) cation is established by magnetic susceptibility measurements of polycrystalline [Fe(CO)(6)][SbF6](2) and [Fe(CO)(6)][Sb2F11](2) between and 300 K. The magnetic impurity formed during synthesis is identified as Fe[SbF6](2) which has iron(II) in high spin (T-5(2g)) ground state. Consistent with a diamagnetic ground state are the single line in the Fe-57 Mossbauer spectrum (i.s. = -0.003(8) mm s(-1) relative to alpha-Fe), obtained on polycrystalline samples and the single sharp line in the C-13 NMR spectrum in DF solution at 178 ppm with J (Fe-57-C-13) of 19.2 Hz.},

Controlled bulk coulometric reduction of 50\% of the content of a CH2Cl2 solution of 1 also produces 2, formed by the reaction of 1 with "RuCl2(dppb)" produced in situ during the electrolysis. Complexes 1 and 2 were characterized by spectroscopic techniques [including electron spin resonance (ESR)], magnetic moments and cyclic voltammetry, and the structure of 1 was determined by X-ray diffraction. The structure shows that the aquo ligand forms hydrogen bonds with two cis-chlorine ligands of the neighboring molecule of the complex; this interaction gives rise to exchange coupling between two Ru(III) centers that is reflected in the ESR spectrum. A species 3 analogous to 1 has been obtained with the diop ligand [diop = (2R,3R)- or (2S,3S)-O-isopropylidene-2,3-dihydroxy-1,4-bis(diphenylphosphino)butane] , on using RuCl2(diop)(PPh3) or [RuCl(diop)](2)(mu-Cl)(3) as precursors.

The fluorometric assay for 2{\textquoteright},7{\textquoteright}-dichlorofluorescein, which is formed by oxidation of a nonfluorescent precursor (2{\textquoteright},7{\textquoteright}-dichlorofluorescin diacetate), was used to assay reactive oxygen species (ROS) production. The chelator Hdpp alone and the aluminum complexes of each chelator, Al(dpp)(3) and Al(nbp)(3), all inhibited basal rates of generation of ROS within a rat cerebral synaptosomal fraction. In the presence of an iron salt (1 mu M FeSO4), a major enhancement of syn aptosomal ROS formation was apparent. However, with the addition of an equimolar concentration of Hdpp, Al(dpp)(3), or Al(nbp)(3), this stimulation was completely abolished. The N-substituted-3-hydroxy-4-pyridinones have been proposed to be of clinical utility for the removal of iron or aluminum from tissues. The clinical potential of this class of chelator may be enhanced by their ability to inhibit iron-related oxidative events. (C) 1998 Elsevier Science Inc.},

Complexes formed by selected metal ions with added organic ligands in 50:50 water/acetonitrile and 50:50 water/methanol under acidic, neutral, and basic conditions were detected using electrospray ionization conditions optimized to best represent solution-phase interactions. Metal species containing acetate, nitrate, and solvent molecules predominated in acidic solution but became less abundant at higher pH. Interactions between metal ions and added organic ligands became more selective with increasing pH, showing the expected preference of hard and soft ligands for metal ions:of the corresponding type. Species distributions also tended toward larger complexes as pH increased. Overall ion yield was greater for aqueous acetonitrile than for aqueous methanol solutions; however, reduction of copper(II) in aqueous acetonitrile resulted in the detection of copper(I) complexes for certain ligands. Experimental results for copper(II) and 8-hydroxyquinoline in 50:50 water/methanol showed good agreement with aqueous speciation predicted using the thermodynamic equilibrium model MINEQL. Detection of neutral complexes was achieved by protonation, deprotonation, or electrochemical oxidation during electrospray.},

These dipyrromethanes are key reagents in two high-yield (2+2)-type syntheses of DPP. 5-Phenyldipyrromethane was formylated to provide 1-formyl- (11) and 1,9-diformyl-5-phenyldipyrromethane (12), and reduction of 11 provided the corresponding hydroxymethyl compound 13, These compounds (11-13), however, were much less efficient precursors to DPP.

In such materials the metal ions are linked by ligand groups to form polymeric chains. Existing theories of the spin transition in crystalline materials are discussed, but we argue that the physical justification of these theories may be inappropriate for polymeric compounds. We describe a possible mechanism in which local strain in the ligand network can drive the transition. A model Hamiltonian is presented and solved and the effects of pressure and dopant concentration on the spin transition are investigated. We also point but that the model describes many of the effects observed in experiments on crystalline materials.},

	abstract = {Two reactions of muonium atoms close to the diffusion-controlled limit were analyzed as a function of solute size and solvent viscosity. With Cr(NCS)(6)(3-) as solute in water, the reaction is an electron spin-conversion process, and the observed rate is taken to be half of the actual encounter rate, because of the quantum mechanical statistical factor and the occurrence of multiple collisions due to the solvent cage effect. The encounter rate deduced is 6.2 x 10(10) M-1 s(-1), which implies a large cross section for the Cr complex. In a second series of experiments, the rate of reaction of muonium with I-2 was compared in water, methanol and n-heptane. The bimolecular rate constants determined are (1.7 +/- 0.3), (7.0 +/- 1.2), and (57 +/- 22) x 10(10) M-1 s(-1), respectively, in these three solvents. This similar to 30-fold change in rate is not matched by the change in the inverse of the solvents{\textquoteright} viscosities, which changed overall by a factor of only 2.4. It looks as if quantum tunneling dominates over classical diffusion in less polar media where muonium is unencumbered by solvent clathration.},

We have shown that Schiff base and amine phenolate ligands exhibit a variety of coordination modes in lanthanide(III) complexes, and that tren-(tris((2-amino)ethyl)amine)-based amine phenolates show selectivity towards later lanthanide(III) ions. By altering the nature of the amine phenolate ligand backbone the coordination mode of the ligand in solution can be easily controlled. Selectivity among lanthanide(III) ions can be controlled by substitution of the parent ligand donor atoms (phenolate oxygen) with donor atoms of a different type (e.g. phosphinate oxygen). By derivatizing the ligand to include more donor atoms and by stiffening the backbone, it is possible to control the aggregation of lanthanide(III) ions (enabling the formation of dimeric lanthanide complexes).},

	abstract = {[Cp*Mo(NO)(CH2SiMe3)(2)] exhibits three principal types of reaction with the various lithium reagents investigated during this study, namely: regioselective deprotonation, reduction, and addition. Deprotonation of the reactant, achieved by treatment with lithium amide reagents, leads ultimately to the formation of the alkylidene {\textquoteright}{\textquoteright}ate{\textquoteright}{\textquoteright} complex [Cp*Mo(NO)(CH2SiMe3)(=CHSiMe3)](2)[Li-2(thf)(3)] (1). While LiN(SiMe3)(2) effects this conversion directly with no detectable intermediates, reaction with 1 equiv of LDA in THF for 15 min deprotonates the Cp* ligand to form the lithium salt of the {\textquoteright}{\textquoteright}tucked-in{\textquoteright}{\textquoteright} ate complex [(eta(5),eta(1)C(5)Me(4)CH(2))Mo(NO)(CH2SiMe3)(2)][Li(thf)(3)] (2) in 40\% isolated yield, Complex 2 slowly converts to the thermodynamically more stable 1 when left as a THF or C6D6 solution at ambient temperature fbr 48 h. Reaction of the dialkyl starting material with either tBuLi or PhLi leads to the production of the alkylidene complex 1 in irreproducible yields (10-50\% NMR; not isolable). A kinetic analysis of the reaction of [Cp*Mo(NO)(CH2SiMe3)(2)] with LiN(SiMe3)(2) indicated that the reaction was first-order in both the lithium and molybdenum reagents, and the activation parameters of Delta H-double dagger = 7,3 +/- 1.0 kcal mol(-1) and Delta S (double dagger) = -34 +/- 3 e.u. suggest an associative process. Treatment of the neutral dialkyl with 1 equiv of LiPPh2, in THF results in a one-electron reduction and production of {[Cp*Mo(NO)(CH2SiMe3)(2)][Li(thf)]}(2) (3). If left in solution, the 17e(-) dialkyl anion 3 is converted to the 18e(-) alkylidene anion 1 by the Ph2P-PPh2 coproduct, which effects the requisite hydrogen-atom abstraction. Finally, addition of a sterically undemanding alkyllithium reagent such as MeLi to the 16e(-) dialkyl reactant leads to the formation of the 18e(-) trialkyl anionic complex [Cp*Mo(NO)(CH2SiMe3)(2)(Me)][Li(thf)(3)] (4). Warming of 4 in a C6D6 solution results in loss of methane and production of 1. In most cases, the chemistry exhibited by the Mo system is duplicated by the analogous W congener, [Cp*W(NO)(CH2SiMe3)(2)]. The solid-state molecular structures of complexes 1 and 4 have been established by single-crystal X-ray crystallographic analyses.},

	abstract = {The laser excitation spectrum of tungsten methylidyne, WCH, has been recorded in the 12 000-15 400 cm(-1) region. A total of 14 vibronic bands of WCH and 16 bands of WCD have been observed in this region. Rotational analysis shows that the ground state is (X) over tilde 3/2((2) Delta), with the substitution structure r(0)(W=C)=1.7366(5) Angstrom and r(0)(C-H)=1.076(5) Angstrom. The excited vibronic levels have been assigned, on the basis of their WCH/WCD isotope shifts and their wavelength resolved fluorescence patterns, to three electronic states, (A) over tilde 3/2((2) Delta), (B) over tilde 1/2((2) Pi), and (C) over tilde 5/2(2 Phi), at 12 090, 13 392, and 14 110 cm(-1), respectively. The wavelength resolved fluorescence spectra have also established the low-lying vibrational levels of the ground state. The ground state bending fundamental lies at 660 cm(-1), while the W-C stretching frequency is 1006 cm(-1); the corresponding frequencies in WCD are 501 cm(-1) and 953 cm(-1), respectively. No evidence for the C-H stretching frequency has been found. Emission has also been observed to a low-lying electronic state, 813 cm(-1) above the (X) over tilde 3/2 state. The pattern of rotationally resolved emission to this state clearly indicates that it is a (4) Sigma(1/2) state. Its bending frequency is 612 cm(-1), and its W-C stretching frequency is 971 cm(-1), indicating a slightly longer bond length than in the (X) over tilde 3/2 state. High resolution cw laser spectra of the (0,0) bands of the two lowest excited electronic states [(A) over tilde 3/2((2) Delta) and (B) over tilde 1/2((2) Pi)] reveal a small splitting of the four principal tungsten isotopes (W-182, W-183, W-184, and W-186) which serves to confirm the presence of tungsten in the carrier. Hyperfine splitting associated with the W-183 nucleus (I = 1/2) has been observed for the (0,0) band of the (A) over tilde 3/2- (X) over tilde 3/2 system, allowing the electron configuration of the ground state to be elucidated.

The magnetic properties were analyzed employing a model for S = 1 which takes into account zero-field splitting and employs a molecular field term to account for weak magnetic exchange. The compounds Ni(pyz)Cl-2 and Ni(py)Cl-2, show metamagnetic behaviour with critical fields of 13 and 2 kOe, respectively, at 2 K. In these compounds nickel ions, linked in chains by bridging chlorides, exhibit intrachain ferromagnetic and interchain antiferromagnetic exchange. In Ni(pyz)Cl-2, bridging pyrazine ligands are considered to provide the pathway for the antiferromagnetic coupling resulting in a high critical field.},

	abstract = {Aluminum (Al) can cause CNS toxicity. The mechanism of its blood-brain barrier (BBB) permeation is poorly understood. In this study, microdialysis was used to determine extracellular fluid (ECF) unbound aluminum distribution between frontal cortex (FC) and blood during steady-state aluminum concentrations. The brain/blood aluminum ratio was determined. Over a 16-fold range of aluminum concentrations (dosed as aluminum citrate), brain/blood aluminum ratios were 0.10-0.15, consistently and significantly <1. Aluminum diffusion cannot account for these results, suggesting the presence of a carrier that moves aluminum out of brain extracellular fluid. These aluminum brain/blood ratios (BBRs) were not significantly different over the range of concentrations studied, suggesting an inability to saturate the carrier. Brain/blood aluminum ratios obtained with four aluminum-hydroxypyridinones were also significantly <1 (0.1-0.3), and were generally significantly different among themselves and from the aluminum citrate BBR. Movement of a BBB permeability marker from blood into brain extracellular fluid suggested partial BBB opening. The aluminum BBRs obtained (all much less than 1), in the presence of a partially opened BBR, suggest an efficient carrier moving aluminum out of brain ECF. Addition of cyanide to the brain microdialysis probe solution significantly increased the Al (citrate) BBR to 1, These results suggest the presence of an efficient, energy-dependent carrier that removes aluminum from brain ECF, either into brain cells or blood.},

The reaction is first-order in both 2 and dpm with the reactivity trend in CHCl3 being X = Cl > Br > I. The activation parameters for the chloride system are Delta H-double dagger = 41 +/- 3 kJ mol(-1) and Delta S-double dagger = -127 +/- 10 J K-1 mol(-1), and for the bromide, Delta H-double dagger = 38 +/- 1 kJ mol(-1) and Delta S-double dagger = -144 +/- 4 J K-1 mol(-1), showing the entropy term is dominant in governing reactivity. Low-temperature NMR studies did not reveal the presence of observable intermediates. 2b and 1b undergo rapid diphosphine ligand exchange with dpm-d(2); with 2b, prior to any S-abstraction, Pd2Br2(mu-S)(dpm)(dpm-d(2)) (7b) and Pd2Br2(mu-S)(dpm-d(2))(2) (8b) are present, while Pd2Br2(dpm)(dpm-d(2)) (3b) and Pd2Br2(dpm-d(2))(2) (4b) are formed, as well as 1b and dpm(S)-d(2), in the abstraction reaction of 2b with dpm-d(2). The distribution of products is close to statistical on the basis of the stoichiometries of the reactants. Reaction of 2b with 1,1{\textquoteright}-bis(diphenylphosphino)ethane (dpmMe) proceeds in an analogous way generating 1b, Pd2Br2(dpm)(dpmMe) (5b), Pd2Br2(dpmMe)(2) (6b), dpm(S), and dpmMe(S). In contrast, 1b undergoes slow diphosphine ligand exchange with dpmMe to form 5b and 6b; 2b undergoes no ligand exchange with dpmMe prior to the S-abstraction reaction. The findings are rationalized in terms of postulated intermediates and transition states that include formulations with three equivalent diphosphines. No sulfur abstraction occurs on treating 2b with PPh(3), PPh(2)Me, or Ph(2)P(CH2)(3)PPh(2).},

Use of 1 equiv of amine per [Ru(II)](2) gives dinuclear Ru2Cl4(dppb)(2)(NH(2)CH(2)Ph) (4a) as a mixture of isomers. The corresponding reactions with dibenzylamine yield only dinuclear products: either Ru2Cl4(dppb)(2)[NH(CH(2)Ph)(2)] (4b), for reactions under H-2, or a mixture of this species and the dealkylation product 4a. The mechanism proposed for formation of the latter involves dehydrogenation of the secondary amine adduct to Ru2Cl4(dppb)(2)[PhCH(2)N=C(H)Ph], followed by hydrolysis of the coordinated imine. Direct reaction of PhCH(2)N=C(H)Ph with 3 under H-2 permits isolation of solely 4b. The findings are of interest also in context of thermal degradation of tertiary amines and hydrogenation of imines catalyzed by Ru ditertiary phosphine complexes.},

Rotational and centrifugal distortion constants have been determined for all species, as well as the nuclear quadrupole coupling constants of S-33 and Ne-21 in Ne-(OCS)-S-33 and Ne-21-OCS, respectively. Harmonic force field analyses have been performed which account for the Variations in the distortion constants between the isotopomers. Effective and ground state average structures have been obtained and are discussed in light of the nuclear quadrupole coupling constants and of dipole moment measurements. The determined coupling constants have provided a means of comparing the effects of perturbation of the electronic structures of both constituents upon complexation. An electrostatic model has been applied to calculate the Ne-21 coupling constants and a possible source of their disagreement with experiment is discussed. (C) 1995 Academic Press, Inc.},

The conversion is initiated by loss of the phosphine ligand from the chromium atom{\textquoteright}s coordination sphere, the most compelling evidence for this step being that addition of excess phosphine (e.g. 4 equiv) to the initial reaction mixture completely inhibits the reaction. Four intermediate complexes which are formed sequentially on the reaction path from 1 to 6 have been detected by IR and ESR spectroscopy. These complexes have been identified as CpCr(NO)(THF)I (2), CpCr-(NO{\textendash}>Mg{CH(2)SiMe(3)})Cl)(THF)I (3), CpCr(NO{\textendash}>Mg{CH(2)SiMe(3)}Cl)(THF)(CH(2)SiMe(3)) (4), and CpCr(NO) (THF)(CH(2)SiMe(3)) (5).

The only site of insertion for tert-butyl isocyanide is the W-C bond, the W-N and W-O linkages being unreactive toward this substrate. In contrast, the preferential site of insertion for the two heterocumulenes, p-tolyl isocyanate, and carbon disulfide, was found to be W-N > W-O > W-C and W-N congruent-to W-C > W-O, respectively. These observations can be rationalized in terms of two different mechanisms being operative, one involving initial adduct formation at the metal center and the other involving direct attack at the tungsten-element bond undergoing the insertion. The tert-butyl isocyanide reactions proceed predominantly via the former mechanism, the p-tolyl isocyanate reactions proceed predominantly via the latter mechanism, and the carbon disulfide reactions proceed via both mechanistic pathways simultaneously. Consistently, a kinetic investigation of the reaction between complex 2 and p-tolyl isocyanate reveals that the reaction is second-order overall and first-order in 2 in the presence of an excess of isocyanate, findings indicative of a simple bimolecular reaction between 2 and the isocyanate. The solid-state molecular structure of Cp*W(NO)(eta2-C{NCMe3}CH2CMe3)(OCMe3) (5), formed by the reaction of 3 with tert-butyl isocyanide, has been established by a single-crystal X-ray diffraction analysis.

	abstract = {The maltolate compound of aluminum (Al), tris(maltolato)aluminum(III), has been demonstrated to be quite toxic after central administration and in cell cultures. However, reports of peripheral Al-maltolate administration in vivo demonstrated un impressive neurological effects. We found no reports of Al-maltolate pharmacokinetics or its distribution into the central nervous system (CNS) after systemic administration. In the present study, we evaluated Al pharmacokinetics in serum and Al distribution into brain extracellular fluid (ECF) in rats following Al-maltolate administration. The pharmacokinetic studies revealed that systemic clearance, elimination half-life and mean residence time were 42 (+/- 5) ml/hr/kg, 2.2 (+/- 0.5) hr and 3.1 (+/- 0.7) hr [mean+/-SD), respectively. The steady state volume of distribution (V-ss) for Al-maltolate was 130 ml/kg. This V-ss suggests that Al-maltolate may exhibit limited distribution outside the vascular compartment, which is estimated to be approximate to 80 ml/kg in these rats. Previously, we used microdialysis (MD) probes to assess Al-citrate distribution into the CNS. MD was utilized in the present study to evaluate the CNS distribution of Al as a result of Al-maltolate administration. MD probes were implanted into the frontal cortex (FC) and jugular vein to sample Al from brain and blood ECF, respectively. Al was not measurable in FC MD probe dialysates after a 0.5 mmol/kg Al (as maltolate) bolus, but could be measured after steady state blood and brain ECF Al concentrations had been achieved. The Al brain/blood ra tio calculated from Al-maltolate steady state brain and blood MD samples was 0.04, significantly less than those calculated for other Al salts at equimolar Al doses.

J. Chem. 72, 1894 (1994)). Twelve anionic sulfonated and seven cationic methylpyridinium porphyrins, usually containing other functional groups (phenyl, pyridyl, nitro- and amino-phenyl), are reported on. Twelve of these porphyrins are new, and all nineteen porphyrins are characterized by H-1 NMR. UV-VIS data are presented for the isolated porphyrins, while mass spectral data are noted for selected compounds. Partition coefficients of the porphyrins in octanol-water, and the accumulation of the porphyrins in HT-29 cells of a human-cancer tumor, were measured and both were inversely related to the charges of the porphyrins. The 11 porphyrins soluble in biological buffer solutions are basically nontoxic to Chinese hamster ovary (CHO) cells in oxic or hypoxic conditions or to aerobic HT-29 cells at the 100 mu M concentration used (which is sometimes limited by solubility). No significant X-ray radiosensitization was observed for selected porphyrins toward CHO cells at the 100 mu M concentrations used, but some photosensitized cell kill (using 630 nm light) was observed using the disodium salt of 5,10-bis(4-pyridyl)-15,20-bis(4-sulfonatophenyl)porphyrin (24).},

Photolysis of toluene solutions of CpCr(NO)(CO)2 in the presence of PPh3 and a source of halogen such as CH2Cl2 results in a 63\% isolated yield of CpCr(NO)(PPh3)Cl. In donor solvents, S, the ESR-active CpCr(NO)(L)X (X = Cl, I) compounds undergo either L or X substitution to form the 17-valence-electron CpCr-(NO)(S)X and [CpCr(NO)(L)(S)+ species, respectively. A kinetic analysis of the reaction of CpCr(NO)(THF)I with PPh3 shows the process to be second-order overall (first-order in each reactant) and associative in nature. The reduction potentials for the various CpCr(NO)(L)X complexes in THF vary from -1.05 to -1.65 V. These reductions are irreversible and are followed by loss of X-. Consistently, reduction of CpCr(NO)(PPh3)I in THF by Zn in the presence of P(OPh)3 affords the 18-valence-electron mixed phosphine-phosphite complex, CpCr(NO)(PPh3)[P(OPh)3]. The redox chemistry of the CpCr(NO)(L)X complexes is thus unusual in that the odd-electron species are substitutionally less labile than are, their 18-electron reduction products.},

The nuclear quadrupole hyperfine structures due to the Cl-35 and Cl-37 nuclei have been resolved, yielding the corresponding nuclear quadrupole coupling constants. The differences in these constants between the inner and outer Cl nuclei, along with the derived geometry and the relatively low centrifugal distortion constants, are consistent with a picture of a rather rigid complex with a significant charge redistribution in the Cl2 monomer on complexation with CO.},

The use of (CO)-C-13 or (CO)-O-18 permits the synthesis of the corresponding isotopically labeled salts. The compound is thermally stable up to 130-degrees-C. The cation has D(infinity h) symmetry, and all seven fundamentals, three Raman and four IR active modes, are observed.

In the C-13 NMR spectrum a single-line resonance at 174 ppm is attributed to ([Au(CO)2]+)-C-13, while the ([Au(CO)]+)-C-13 chemical shift changes from 162 ppm in HSO3F to 158 ppm in magic acid (HSO3F/SbF5). The resonances for ([Au(CO)2]+)-C-13 and ([Au(CO)]+)-C-13 in the same solution are found to undergo coalescence at elevated temperature indicative of slow CO exchange. The coalescence temperature is solvent dependent, 325 K in HSO3F and 395 K in the more dilute HSO3F/SbF5 mixture. Attempts to recrystallize [Au(CO)2] [Sb2F11] from acetonitrile result in the formation of single crystals of [Au(NCCH3)2][SbF6] instead. The compound crystallizes in a cubic unit cell, space group Pa3BAR, with a = 10.250 (2) angstrom and Z = 4.

Each of the complexes 1-3 is derived in a sequential manner from its precursor by incorporation of an additional p-tolyl isocyanate fragment or molecule. The spectroscopic properties of these organometallic imido complexes are consistent with their possessing three-legged (1 and 2) and four-legged (3) piano-stool molecular structures. These conclusions have been confirmed by single-crystal X-ray crystallographic analyses of 2 and 3. Crystal data for 2: triclinic},

The reaction of 1 with Os3(CO)12 yields Fe(eta-C5H4S)2(S)Os2(CO)6 (5) in low yield in refluxing cyclohexane and four products in moderate to low yields in refluxing toluene. These compounds were identified as the diosmium species Fe(eta-C5H4S)2Os2(CO)8 (6), the triosmium species Fe(eta-C5H4S)2Os3(CO)10 (7), and the tetraosmium species Fe(eta-C5H4S)2(mu-3-S)Os4(CO)11 (8) and Fe(eta-C5H4S)2(mu-3-S)2Os4(CO)10 (9). Only complexes 4 and 8 were characterized by using X-ray crystallography. The common sawhorse geometry is found for 4, with the Fe(eta-C5H4S)2 group bridging the two Ru(CO)3 moieties. The osmium cluster 8 consists of a mu-3-S ligand bridging a spiked triangle of osmium atoms with the Fe(eta-C5H4S)2 ligand bridging the spike Os-Os bond.
