	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.

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 = {Cp*W(NO)(n-alkyl)(eta(3)-allyl) complexes result from the selective activations of the terminal C-H bonds of alkanes. Consequently, the reactions of prototypical members of this family of complexes with a range of electrophilers and nucleophiles have been explored with a view to developing methods for functionalizing the newly formed alkyl ligands. The two principal complexes investigated in this regard have been Cp*W(NO)CH2SiMe3)(eta(3)-CH2CHCHMe) (1) and Cp*W(NO)(CH2C6H5)-(eta(3)-CH2CHCHMe) (2). In has been found that treatment of 1 and 2 with the oxidant I-2 at - 60 degrees C produces Cp*W(NO)I-2 and terminallly functionalized ICH2SiMe3 and ICH2C6H5, respectively. Oxidation of 1 by H2O2 also results in the loss of the allyl ligand and production of known oxo peroxo complex Cp*W(O)(eta(2)-O-2)(CH2SiMe3). Treatment of 1 and 2 with electrophiles affords the products resulting from addition of the electrophile to the electron-rich terminus of the sigma(-)pi distorted allyl ligands in the reactants. Thus, reagents of the type E-X (E = triphenylcarbenium, H. catecholborane; X = Cl, BF4) liberate CH3CH = CHCH2E and form the organometallic products Cp*W(NO)(X)(CH2SiMe3) and cp*W(NO)(X)(CH2C6H5), respectively. Exposure of the tungsten alkyl allyl complexes to isocyanide reagents leads to the formation of complexes insertion of isocyanide into the tungsten-allyl linkages. For instance, reaction of 1 with 2,6-xylylisocyanide produces Cp*w-(NO)(CH2SiMe3)(eta(2)-CH3CH2CHCHC = NC6H3Me2) (4b). A similar reaction of 2 with 2.6-xylylisocyanide affords both unconjugated and conjugated isocyanide insertion products, while treatment of 2 with n-butylisocyanide produces primarily the conjugated product. Finally. exposure of these tungsten alkyl allyl complexes to 1000 psi of CO gas generally results in the desired migratory insertion of the CO into the metal-alkyl linkages to form acyl compounds. Hence, 1 is first converted into Cp*W(NO)-(C(O)CH2SiMe3)(eta 3-CH2CHCHMe), which then subsequently transforms into isolable Cp*W(NO)-(C(O)CH3)(eta 3-CH2CHCHMe) (7). Interestingly, 2 does not react with CO under these experimental conditions. Nevertheless, the generality of this mode of reactivity is established by the fact that similar treatment of four other Cp*(W)(NO)(CH2CMe3)(eta(3)-allyl) complexes with CO gas at elevated pressures does afford the corresponding acyl products (8-11). All new organometallic complexes have been characterized by conventional spectroscopic and analytical methods, and the solid-state molecular structures of several compounds have been established by X-ray crystallographic analyses.},

The elastic cross sections employed are a hard sphere cross section and the Maxwell molecule cross section. Reactive cross sections which model reactions with and without activation energy are used. A detailed comparison is carried out with these solutions of the Boltzmann equation and the approximation introduced by Cukrowski and coworkers [J. Chem. Phys. 97 (1992) 9086; Chem. Phys. 89 (1992) 159; Physica A 188 (1992) 344; Chem. Phys. Lett. A 297 (1998) 402; Physica A 275 (2000) 134; Chem. Phys. Lett. 341 (2001) 585; Acta Phys. Polonica B 334 (2003) 3607.] based on the temperature of the reactive particles. We show that the Cukrowski approximation has limited applicability for the large class of reactive systems studied in this paper. The explicit time dependent solutions of the Boltzmann equation demonstrate that the CE approach is valid only for very slow reactions for which the corrections to the equilibrium rate coefficient are very small.

	abstract = {An important mechanism for ice cloud formation in the Earth{\textquoteright}s atmosphere is homogeneous nucleation of ice in aqueous droplets, and this process is generally assumed to produce hexagonal ice(1,2). However, there are some reports that the metastable crystalline phase of ice, cubic ice, may form in the Earth{\textquoteright}s atmosphere(3-5). Here we present laboratory experiments demonstrating that cubic ice forms when micrometre-sized droplets of pure water and aqueous solutions freeze homogeneously at cooling rates approaching those found in the atmosphere. We find that the formation of cubic ice is dominant when droplets freeze at temperatures below 190 K, which is in the temperature range relevant for polar stratospheric clouds and clouds in the tropical tropopause region. These results, together with heat transfer calculations, suggest that cubic ice will form in the Earth{\textquoteright}s atmosphere. If there were a significant fraction of cubic ice in some cold clouds this could increase their water vapour pressure, and modify their microphysics and ice particle size distributions(5). Under specific conditions this may lead to enhanced dehydration of the tropopause region(5).},

With 9-BBN, hydroboration of the Ta2N2 unit occurs via B-H addition, which in turn triggers a cascade of reactions that result in N-N bond cleavage, ancillary ligand rearrangement involving silicon group migration, and finally elimination of benzene from the N-Ph group and a B-H moiety to generate the imide-nitride derivative. In the presence of excess 9-BBN, the Lewis acid - base adduct of the imide-nitride ([NP mu-N]Ta(=NBC8H14)(mu-NB(H)C8H14)Ta[NPN]) is formed. A similar set of reactions is observed for dicyclohexylborane (Cy2BH), which hydroborates the dinitrogen complex to generate [NPN]Ta(H)(mu-eta(1):eta(2)-NNBCy2)(mu-H)(2)Ta[NPN], followed by loss of H-2 and silicon group migration to yield the imide-nitride [NP mu-N]Ta(=NBCy2)(mu-N)(Ta[NPN]. With thexyl borane (H2BCMe2CHMe2), a similar sequence of reactions is suggested starting with hydroboration to generate [NPN]Ta(H)(mu-eta(1):eta(2)-NNB(H)C6H13)(mu-H)(2)Ta[NPN], followed by loss of H-2 and ancillary ligand rearrangement. When bis(pentafluorophenyl)borane (HB(C6F5)(2)) is used, no hydroboration of coordinated N-2 is observed, rather simple adduct formation to give ([NPN]Ta)(2)(mu-eta(1):eta(2)-NN-B(H)(C6F5)(2))(mu-H)(2) occurs.},

A common synthetic route, the oxidative carbonylation of either Fe(CO)(5) (XeF2 as the oxidizer) or M-3(CO)(12) (M = Ru, Os) (F-2 as the oxidizer) in the conjugate Bronsted-Lewis superacid HF/BF3, was employed.

The molecular structures Of [M(CO)(6)][BF4](2) (M = Fe, Os) were obtained by single-crystal X-ray diffraction at 100 K. X-ray powder diffraction data for [M(CO)(6)][BF4](2) (M = Ru, Os) were obtained between 100 and 300 K in intervals of 50 K. All three salts are isostructural and crystallized in the tetragonal space group I4/m (No. 87). As for the corresponding [M(CO)(6)][SbF6](2) salts (M = Fe, Flu, Os), similar unit cell parameters and vibrational fundamentals were also found for the three [BF4](-) compounds. For the structurally characterized salts [M(CO)(6)][BF4](2) (M =. Fe, Os), very similar bond parameters for both cations and anions were found. Hence, the invariance of structural and spectroscopic properties Of [M(CO)(6)](2+) cations (M = Fe, Ru, Os) extended from the fluoroantimonates [Sb2F11](-) and [SbF6](-) as counteranions also to [BF4](-).},

The two end products are diastereomeric rotational isomers in which N-N bond cleavage has occurred with an Al(Bu-i)H group attached to one of the nitride atoms. The reaction proceeds through addition of DIBAL to 1 to generate a thermally sensitive intermediate that has been characterized in solution as the result of Al-H addition across the TaN2 moiety, namely, ([NPN]TaH)(mu-eta(1):eta(2)-NNA1(i)Bu(2))(mu-H)(2)(Ta[NPN), 2. This material subsequently rearranges via a second thermally labile intermediate to ultimately generate two diastereomeric end products that show N-N bond cleavage, loss of H-2, loss of an aluminum isobutyl group, and NPN ligand migration from tantalum to aluminum. Both of these complexes have been isolated in crystalline form and analyzed by single-crystal X-ray diffraction.

In the EPR spectrum of 5, an additional five-line super-hyperfine splitting pattern was observed at 77 K, caused by additional interaction of the unpaired electron with ligand nitrogen atoms (I=1), indicating that the structure of 5 was retained in dimethyl sulfoxide solution.

In an effort to develop new discotic liquid crystals based on these compounds, a series of macrocycles with peripheral alkoxy groups of varying length have been prepared. The synthesis and mechanism of formation have been probed by isolation of oligomeric intermediates. A single-crystal X-ray diffraction study of one macrocycle revealed a nonplanar, strongly hydrogen-bonded structure. To our surprise, even with very long substituents, the macrocycles were not liquid crystalline. This has been rationalized by ab initio calculations that indicate the macrocycles are undergoing rotation of the dibydroxydiiminobenzene rings that may not allow a stable discotic liquid crystalline phase. These results provide new insight into the formation and properties of these large macrocycles and may provide guidance to developing stable liquid crystalline materials in the future.</p>},

The first approach is conventionally used to improve corrosion protection, but alternatives are needed because of environmental concerns with Cr(VI). Variations in conditions for application of the final rinse, especially through changes in solution concentration, were compared by measuring polarization curves, which provide an indication of corrosion stability. These comparisons were related to coating morphology, which was studied using scanning electron microscopy (SEM), and to studies of chemical composition with X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray (EDX) spectroscopy. Immersion tests in NaCl solution were applied to post-treated zinc phosphate coatings that had been formed on mirror-polished alloy surfaces. Overall, the post-treatment in 4\% BTSE at 25 degreesC appears to provide a comparable corrosion resistance to that found when the final rinse is done in a conventional CrO3 Solution (concentration 0.5 g/l) at 70 degreesC. At the microstructural level, initial observations were also made for comparing the effects of the post-treatments at protecting alloy matrix areas adjacent to Al-Cu-Mg second-pbase particles.

Dc magnetic susceptibility studies at an applied field of 1000 G reveal that on cooling from room temperature, the material undergoes two structural phase transitions designated alpha {\textendash}> beta, and beta {\textendash}> gamma at 151 and 133 K, respectively.

Magnetic susceptibility and bond length data reveal that in the gamma-phase one in three six-coordinate sites corresponds to spin singlet ground-state iron(II); i.e., the overall alpha {\textendash}> gamma process involves a spin-crossover transition such that at least 1/6 of the iron sites in the gamma-phase correspond to S = 0.

In this review, the activation of molecular nitrogen by transition metal complexes is reviewed with the view to present new kinds of transformations for coordinated dinitrogen. Moreover, some reaction types that are as yet unknown are outlined to try and stimulate further research in this area. (C) 2003 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.},

Blood levels of vanadium were determined at regular intervals, to 72 h, following i.p. injection. All complexes tested exceeded vanadyl sulfate in glucose-lowering ability; this effect was not correlated, however, with blood vanadium levels. Analysis of the pharmacokinetics of the disappearance of [ethyl-1-C-14]BEOV after an oral gavage dose (50 mg kg(-1), 0.144 mmol kg(-1), in a 10 mL kg(-1) volume of 1\% CMC solution) indicated clearly that metal ion-ligand dissociation took place relatively soon after oral ingestion of the complex. Half-lives of fast phase uptake and slow phase disappearance for C-14 and V were calculated from a two-compartment model for whole blood, plasma, liver, kidney, bone, small intestine, and lung, ranging from 17 min (t(1/2)alpha for C-14, liver) to 30 days (t(1/2)beta for V, bone). Curves of disappearance of plasma and whole blood C-14 and V diverged dramatically within the first hour after administration of the vanadium complex.},

The chemical shifts of the guests and the thermodynamic and kinetic values for templation suggest that binding is key, often tight, and that the guest determining step is formation of the last covalent bond. The molecular dynamics of guests as well as the conformational dynamics of both hosts and guests further addresses nature of the recognition between host and guest. Finally, we were surprised to discover that water can bind reversibly to the trimer carceplexes, which will have ramifications to any inner phase reactions conducted inside the cage.},

Likewise, (trimpsi)V(NO)Br-2 (2) and (trimpsi)V(NO)\(2) (3) are formed by the reactions of (trimpsi)V(CO)(2)(NO) with Br-2 and l(2), respectively.

The reaction of (trimpsi)V(CO)(2)(NO) with 2 equiv of CINO forms 1 in low yield, but the reactions of (trimpsi)M(CO)(2)(NO) (M = Nb, Ta) with 1 equiv of CINO generate (trimpsi)M(NO)(2)Cl (M = Nb, 6; Ta, 7). Complexes 6 and 7 are thermally unstable and decompose quickly at room temperature; consequently, they have been characterized solely by IR and P-31{H-1} NMR spectroscopies. All other new complexes have been fully characterized by standard methods, and the solid-state molecular structures of 1.3CH(2)Cl(2), 4.(3/ 4)CH2Cl2, and 5.THF have been established by single-crystal X-ray diffraction analyses. A convenient method of generating (ClNO)-N-15 has also been developed during the course of these investigations.},

This medium allows for trivial separation of the trans-stilbene product which precipitates after the reaction mixture is cooled. The bimetallic precursors are more active than predicted from the sum of the activities of complexes chosen to mimic their mono-metallic "half units," suggesting some degree of intermetallic cooperativity during the reaction. A non-linear dependence of initial rate on catalyst concentration implies, however, that the complexes do not remain intact, and may be involved in dissociative equilibria with non-dmapm containing monometallic components that are more active species for the Heck coupling. The complexes are slowly degraded by oxidation at a phosphorus centre. A general index for quantifying the degree of intermetallic cooperativity during a catalytic cycle is proposed and its utility and limitations are discussed.},

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.},

(TKF)2(where [NPN] = PhP(CH2SiMe2NPh)(2)). The reaction of [NPN]Li-2. (THF)(2) with TaMe3Cl2 produces [NPN]TaMe3, which reacts under HZ to yield the diamagnetic dinuclear Ta(IV! tetrahydride ([NPN]Ta)(2)(mu -H)4 This hydride reacts with N-2 with the loss of H-2 to produce ([NPN]Ta(mu -H))(2)(mu-eta (1):eta (2)-N-2), which was characterized both in solution and in the solid state, and contains strongly activated Nz bound in the unprecedented side-on end-on dinuclear bonding mode. A density functional theory calculation on the model complex [(H3P)(H2N)(2)Ta(mu -H)](2)-mu-eta (1):eta (2)-N-2) provides insight into the molecular orbital interactions involved in the side-on end-on bonding mode of dinitrogen. The reaction of ([NPN]Ta(mu -H))(2)(mu-eta (1):eta (2)-N-2) with propene generates the end-on bound dinitrogen complex ([NPN]Ta(CH2CH2CH3))(2)(mu-eta (1):eta (1)-N-2), and the reaction of [NPN]Li-2. (THF)(2) with NbCl3-(DME) generates the end-on bound dinitrogen complex ([NPN]NbCl)(2)(mu-eta (1):eta (1)-N-2). These two end-on bound dinitrogen complexes provide evidence that the bridging hydride ligands are responsible for the unusual bonding mode of dinitrogen in ([NPN]Ta(mu -H))(2)(mu-eta (1):eta (2)-N-2). The dinitrogen moiety in the side-on end-on mode is amenable to functionalization; the reaction of ([NPN]Ta(mu -H))(2)(mu-eta (1):eta (2)-N-2) with PhCH2Br results in C-N bond formation to yield [NPN]Ta(mu-eta (1):eta (2)-N2CH2Ph)(mu -H)(2)TaBr[NPN].

	abstract = {The structure of L-ribulose-5 -phosphate 4-epimerase from E. coli has been solved to 2.4 Angstrom resolution using X-ray diffraction data. The structure is homo-tetrameric and displays C-4 symmetry. Each subunit has a single domain comprised of a central beta -sheet flanked on either side by layers of alpha -helices. The active site is identified by the position of the catalytic zinc residue and is located at the interface between two adjacent subunits. A remarkable feature of the structure is that it shows a very close resemblance to that of L-fuculose-1-phosphate aldolase. This is consistent with the notion that both enzymes belong to a superfamily of epimerases/aldolases that catalyze carbon-carbon bond cleavage reactions via a metal-stabilized enolate intermediate. Detailed inspection of the epimerase structure, however, indicates that despite the close overall structural similarity to class II aldolases, the enzyme has evolved distinct active site features that promote its particular chemistry.},

Specifically, Mg was deposited on a layer of Nafion with incorporated Ru(bpy)(3)(2 +), and this was itself deposited on PPV-coated ITO. The morphology of Nafion, which is dictated by the strongly hydrophilic and hydrophobic groups that compose it, is indicated to rearrange with the incorporation of Ru(bpy)(3)(2 +) this rearrangement appears reinforced when a thin film is deposited on PPV. The Mg deposition results in substantial changes in XPS spectra, in part due to a direct interaction with the fluorocarbon backbone of Nation. (C) 2001 Elsevier Science B.V. All rights reserved.},

The reaction of 1 with 2 equiv of LiCH2-EMe3 (E = C, Si) produces a similar equilibrium mixture as observed for the benzyl analogues, consisting of [P2Cp]ZrCl2(CH2EMe3) (7), [P2Cp]Zr(CH2EMe3)(3) (8), and [P2Cp]ZrCl(CH2EMe3)(2) (9). Thermolysis of this mixture yields [P2Cp]Zr=CHEMe3(Cl) (6). A kinetic analysis conducted on 9 (E = Si) indicated a first-order reaction from which the activation parameters Delta H double dagger = 6(1) kcal mol(-1) and Delta S double dagger = -62(5) cal mol(-1) K-1 were obtained. The results indicate that reaction rates follow the order CH2Ph > CH2SiMe3 > CH2CMe3, an exact reversal of the trend for the homoleptic Ta systems Ta(CH2R)(5). The role of phosphine coordination is discussed to account for this trend. A crystal structure determination obtained for 6b reveals an alpha-agnostic interaction and a structure analogous to that of 5.},

	abstract = {The reaction of square-planar, high-spin CrR[N(SiMe2CH2PPh2)(2)] (R = Me, CH2SiMe3) with alkyl halides (MeI, CF3CH2I, MeBr, PhCH2Cl) generates one-electron oxidation products Cr(R)X[N(SiMe2CH2PPh2)(2)], unusual examples of five-coordinate chromium(III) complexes. Cr(Me)Br[N(SiMe2CH2PPh2)(2)] and Cr(CH2SiMe3)Cl[N(SiMe2CH2PPh2)(2)] have structurally characterized. Alkylation of the latter complex with LiCH2SiMe3 gave a five-coordinate Cr(III) dialkyl complex Cr(CH2SiMe3)(2)[N(SiMe2CH2PPh2)(2)](2), which was structurally characterized as well. Attempts to isolate sterically unencumbered Cr(III) dialkyl (e.g., dimethyl) complexes resulted in decomposition. Addition of an excess of PhCH2Cl to {[(Ph2PCH2SiMe2)(2)N]Cr}(2)(mu-Cl)(2) resulted in halide-transfer to form CrCl2(TNF)[N(SiMe2CH2PPh2)(2)] in low yield. Reaction of the low-spin CrCp[N(SiMe2CH2PPh2)(2)] complex with PhCH2Cl, however, gave both Cr(Cp)(CH2Ph)[N(SiMe2CH2PPh2)(2)] and Cr(CP)Cl[N(SiMe2CH2CH2PPh2)(2)]. The five five-coordinate Cr(III) alkyl halide complexes do not polymerize ethylene at 60 degrees C and 1 atm; the dialkyl complex Cr(CH2SiMe3)(2)[N(SiMe2CH2PPh2)(2)] does catalyze polyethylene formation but is quickly deactivated. A discussion comparing the structural distortions observed in these five-coordinate high-spin d(3) Cr(III) complexes with those observed in the analogous low-spin d(6) Ir(III) complexes is presented.},

	abstract = {This paper deals with the organometallic chemistry of the trivalent second-row transition metals of groups 4-6, namely, Zr, Nb, and Mo, with the cyclopentadienyldiphosphine ligand [eta(5)-C5H3-1,3-(SiMe2CH2PR2)(2)], abbreviated as [(P2Cp)-P-R] (where R = i-Pr and Ph). The Zr(IV) complex [i-PrP2Cp]ZrCl3 undergoes reduction with Na/Hg to form the trivalent Zr derivative, [i-PrP2Cp]ZrCl2, which undergoes a metathetical reaction with MeMgBr to yield the monomethyl derivative [i-PrP2Cp]Zr(CH3)Cl. The reaction of the Zr(III) complex [i-PrP2Cp]ZrCl2 with excess carbon monoxide results in disproportionation to the Zr(IV) complex, [i-PrP2Cp]ZrCl3, and the Zr(II) compound [i-PrP2Cp]Zr(CO)(2)Cl. This reaction is reversible, and upon removal of CO the starting material, [i-PrP2Cp]ZrCl2 is formed. The preparation of the diamagnetic Nb(III) complex [(P2Cp)-P-R]NbCl2 is achieved by the reaction of NbCl3(DME) with [(P2Cp)-P-R]Li. [(P2Cp)-P-R]NbCl2 complexes react with excess CO to form the CO adducts whose solid-state structures have been determined. The Nb(IV) derivatives [(P2Cp)-P-R]NbCl3 are formed via the reaction of [(P2Cp)-P-R]NbCl2 with PbCl2. These complexes can also be produced when Nb(O)Cl-3(THF)(2) is allowed to react with excess [(P2Cp)-P-R]Li. These Nb(IV) derivatives are ESR active, and their solid-state molecular structures show distorted octahedral geometries around the Nb center. MoCl3(THF)(3) reacts with [(P2Cp)-P-R]Li to generate the corresponding Mo(III) complexes [(P2Cp)-P-R]MoCl2. These compounds are low-spin, paramagnetic complexes as evidenced by their ESR spectra.},

The solution H-1- and P-31{H-1}-NMR spectra are consistent with a C-20 symmetric species in solution. The X-ray crystal structure shows the hydride to be monomeric, and free from interaction with either salt (LiCl) or external base (Et2O). The coordination of both phosphines of the macrocycle to the metal center is found in the solid state. Solution molecular weight measurements are consistent with a monomeric structure. The gallium hydride syn-GaH[P2N2] (5) is synthesized by the addition of LiGaH4 to syn-MCl[P2N2] (M = Ga (2), In (3)). This species is unstable and could only be characterized in solution. Reduction of syn-MCl[P2N2] (M = Ga (2), In (3)) with KC8 yields the reduced, dimeric species {syn-M[P2N2]}(2) (M = Ga (6), In (7)). The solution H-1- and P-31{H-1}-NMR spectra are consistent with C-2v symmetric species in solution. The X-ray crystal structures of the gallium and indium complexes confirm the presence of unsupported metal-metal bonds in both cases. The features of the solution H-1- and P-31{H-1}-NMR spectra suggest that both dimers are fluxional in solution. (C) 1999 Elsevier Science S.A. All rights reserved.},

In both media, ketones bearing methyl substituents alpha to the benzoyl group undergo stereoselective Yang photocyclization to afford endo-arylcyclobutanols. Quantum yield and quenching studies in solution show that the reactions are efficient triplet-mediated processes. Asymmetric induction studies were carried out by providing the reactants with carboxylic acid substituents to which "ionic chiral auxiliaries" were attached through salt formation with optically active amines. Irradiation of the salts (17 in total) in solution gave racemic cyclobutanols, but in the crystalline state, moderate to near-quantitative enantiomeric excesses were obtained. Single crystal X-ray diffraction studies were successfully performed on 10 neutral ketones and four salts. This allowed the reactive gamma-hydrogen atoms to be identified and the distance and angular parameters associated with their abstraction to be tabulated. For the 14 compounds whose crystal structures were determined, the average value of d, the C=O ... H abstraction distance, was 2.61 +/- 0.07 Angstrom, and the values of omega (the gamma-hydrogen out-of-plane angle), Delta (the C=O ... H, angle) and a (the C-H-gamma...

Since the absolute configuration of the ionic chiral auxiliary in this case was known, this permitted the absolute steric course of the reaction to be mapped by X-ray crystallography and the abstracted gamma-hydrogen to be identified unequivocally. In addition, the crystal structure of a partially reacted crystal containing 60\% product and 40\% reactant was successfully determined. This showed that the two compounds in the mixed crystal have nearly identical shapes and orientations, thus accounting for the single crystal nature of the process.

Claisen-type intramolecular condensation of pyropheophorbide a methyl ester (2) afforded the common intermediate enol 3. Chlorin 1 and enol 3 have a propensity to undergo exocyclic ring opening by ionic bases. The organic base DBU was found to be an efficient reagent for promoting the asymmetric hydroxylation of these chlorins, using N-sulfonyloxaziridines, without cleavage of the exocyclic rings. Model studies for hydroxylactonization have shown that periodate oxidation of hydroxy ketone 10 stereoselectively and predominantly forms hydroxy lactone 17(S). Periodate oxidation of alpha-hydroxy 1,3-diketone 4(R) and/or 4(S) to furnish hydroxy lactone 5(R) and diketone 7 was found out to be regioselective, and the site of reaction depends on the appropriate choice of reaction media.

In this work, oxygen is considered to cause removal of phosphine as its oxide, formation of intermediate dioxygen complexes (followed by oxygenation of Ru-Si= to an Ru-O-Si= moiety with elimination of disiloxane) and possible formation of Ru(IV) species. The studies include the characterization of isolated intermediates (well defined complexes or their mixtures) from an RuCl2(PPh(3))(3)-HSi(OC2H5)(3) system and general mechanisms for the hydrosilylation of alkenes in the presence of Ru(II) precursors are discussed.},

In water, the ligand coordinates in a tridentate fashion through the three phenolate oxygen atoms to give mono- and bis(ligand) complexes. The bis complexes are proposed to be 7-coordinate containing one bound water as evinced by O-17 NMR experiments on the Dy3+ complex. while the mono complexes are proposed to have a coordination number of eight or nine. The stepwise formation constants for the 1:1 and 2:1 (L:M) complexes have been measured at 25 degrees C (mu = 0.16 M NaCl) for Nd3+ (log K-1 = 6.41, log K-2 6.34), Gd3+ (log K-1 = 6.67, log K-2 = 7.69), Ho3+ (log K-1 = 7.67, log K-2 = 8.75), and Yb3+ (log K-1 = 8.53, log K-2 = 9.73). The formation constants show an increasing affinity and an unprecedented selectivity for the heavier lanthanides (beta(2(yb)) - beta(2(Nd)) = 10(5.5)). Furthermore, the stepwise stability constant for the 2:1 complex is increasingly greater than that for the 1:1 complexes of Gd3+, Ho3+, and Yb3+, while K-1 and K-2 for the 1:1 and 2:1 complexes of Nd3+ are approximately the same. Solution calorimetry shows that the selectivity for the heavier lanthanides is an enthalpic effect (Delta H-beta 2 = -45.11 (Yb) and -13.71 kJ . mol(-1) (Nd)), while the anomalous behavior in formation constants (K-2 > K-1) is predominantly entropic (Delta S-2 > Delta S-1) and is rationalized in terms of salvation of the complexes, Lanthanum(III) forms only the 1:1 complex (log K = 5.65) which precipitates from solution.},

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 preparation of a series of dinuclear complexes of zirconium and tantalum is presented in an effort to determine factors involved in the coordination mode of the bridging dinitrogen ligand. Reduction of ZrCl3[N(SiMe2-CH2PR2)2] (R = Pr(i) and B(t)) with Na/Hg under N2 generate the corresponding dinitrogen complexes {[(R2PCH2-SiMe2)2 SiMe2)2N]ZrCl}2(mu-eta2:eta2-N2); the X-ray crystal structure of the dark blue derivative having R = Pr(i) shows that the dinitrogen unit is bridging in a planar side-on bonding mode. The N-N bond distance is 1.548(7) angstrom, which is the longest such distance for any dinitrogen complex reported. Molecular orbital calculations on this molecule indicate that the N2 unit bonds in a side-on fashion due to the unavailability of one of the d orbitals on each zirconium that would normally be involved in a pi-bond with the antibonding pi*-orbitals of the N2 moiety. This particular zirconium d orbital is unavailable due to the ancillary tridentate ligand which positions the amide donor (and the chloride) to overlap effectively with this d orbital. The results of this MO study also show that the HOMO has delta-symmetry. When the related derivative Zr(eta5-C5H5)Cl2[N(SiMe2CH2PPri2)2] is reduced under N2, the corresponding dinuclear derivative {[(Pri2PCH2SiMe2)2N]Zr(eta5-C5H5)}2(mu-eta1:eta1-N2) has the bridging dinitrogen unit end-on. In this case, the MO analysis shows that the cyclopentadienyl ligand overlaps with that zirconium d orbital which could form the delta-molecular orbital of the side-on mode; as a result, the end-on form is generated. A similar argument can be used to rationalize the end-on binding mode of the dinitrogen unit in the related tantalum derivatives {[(Pri2PCH2SiMe2)2N]Ta=CHR}2(mu-eta1:eta1-N2) (R = Bu(t), Ph), since now the alkylidene unit effectively overlaps with the same d orbital Crystals of {[(Pri2PCH2-SiMe2)2N]ZrCl}(mu-eta2:eta2-N2)-CH3C6H5 are monoclinic},

	abstract = {Gas-phase mu-SR studies of dense methane up to 10 mol L-1 and of propane at low densities, up to 0.2 mol L-1, are reported. It is found that the diamagnetic polarization, P(D), increases in both gases with pressure, with a related decrease seen in the muonium polarization, P(Mu). The initial increase seen in P(D) at low densities is attributed to hot-atom (Mu*) abstraction and substitution reactions. Comparisons with both hot-tritium (T*) and epithermal H* reactions in the alkanes reveal substantial isotope effects. In the case of CH4, a continued increase in P(D) at higher densities is likely due to a proton-transfer reaction from the molecular ion CH4Mu+ in the radiolysis track, forming CH3Mu, rather than to hot-atom reactions. Extrapolation of the present trend with density gives agreement with the value of P(D) found in liquid CH4, indicating that the diamagnetic muon polarization in dense alkanes depends primarily on density rather than on temperature or phase.},
