	abstract = {Treating phosphorus pentachloride with catechol (3 equiv) followed by the addition of dimethylsulfoxide (DMSO) or dimethylformamide (DMF) affords isolable bronsted acids of tris- (o-phenylenedioxy)phosphate anion, [p(1,2-O2C6H4)(3)](-). Specifically. H(DMSO)(2)[P(1,2-O2C6H4)(3)] and H(DMF)(2)[P(1,2-O2C6H4)(3)] have been isolated as crystalline solids. The downfield shifts of the acidic proton in their H-1 NMR spectra are consistent with its expected high acidity. The molecular structures of H(DMSO)(2)[P(1,2-O2C6H4)(3)] and H(DMF)(2)[P(1,2-O2C6H4)(3)] reveal that the protons in each are O-bound by either DMSO (x2) or DMF (x2). The N-H stretching frequency for the Oct(3)NH[P(1,2-O2C6H4)(3)] ((V) over bar (N-H) =3129 cm(-1)) is identical to that observed for trioctylammonium tetrafluoroborate ((v) over bar (N-H) = 3129 cm(-1)), suggesting that the basicity of these two weakly coordinating anions is similar. A preliminary investigation of the effectiveness of H(DMF)(2)[p(1,2-O2C6H4] in the protonolysis of metal-alkyl bonds was undertaken. Treating (dppe) pdMe(2) [dppe = 1,2-bis(diphenylphosphino)ethane] with H(DMF)(2)[P(1,2-O2C6H4)(3)] affords either [(dppe)pd(NCMe)Me][P(1,2-O2C6H4)(3) (1:1 ratio) or [(dppe)pd(NCMe)(2)(][P(1,2-O2C6H4)(3)](2) (1:2 ratio), both of which are structurally characterized.},

	abstract = {A new method is presented for metalation of a wide range of free-base, neutral, cationic, and anionic porphyrins in refluxing dimethylformamide (DMF) using an easily prepared [Ru(DMF)(6)](OTf)(3) complex, and comparisons are made with the more familiar metalation procedure using Ru-3(CO)(12). Both procedures generate Ru-II(porp)(CO)L complexes (L = solvent); use of the Ru-III-triflate precursor gives yields comparable to, or greater than, those obtained with the carbonyl, and generates no Ru-chlorin impurities. Mechanistic studies on the meso-tetraphenylporphyrin system reveal that the DMF furnishes the CO, which in the presence of essential water reduces the metal, and metalation likely occurs via a Ru-II-CO species. Corresponding metalation of tetradentate Schiff-bases gives trans-[Ru-III(Schiff-base)(DMF)(2)]OTf complexes in yields of similar to 50\%, a limitation being the accompanying hydrolysis of the Schiff-base through the presence of trace water.},

	abstract = {Early transition metal complexes employing a diamido N-heterocyclic carbene (NHC) ligand set (denoted [NCN]) render the centrally disposed NHC moiety stable to dissociation. Aminolysis reactions with the mesityl-substituted ligand precursor ((Mes)[NCN]H-2) and M(NMe2)(4) (M = Zr, Hf) provide bis(amido)-NHC-metal complexes that can be further converted to chloro and alkyl derivatives. Activation of (Mes)[NCN]M(CH3)(2) with [Ph3C][B(C6F5)(4)] yields {(Mes)[NCN]MCH3} {B(C6F5)(4)}, which is surprisingly inactive for the polymerization of 1-hexene. The zirconium cation did, however, show moderate ability to catalytically polymerize ethylene. The hafnium dialkyls are thermally stable with the exception of the diethyl complex, (Mes)[NCN]Hf(CH2CH3)(2), which undergoes P-hydrogen transfer and subsequent C-H bond activation with an ortho-methyl substituent on the mesityl group. The hafnium dialkyl complexes also insert carbon monoxide and substituted isocyanides to yield eta(2)-acyls and eta(2)-iminoacyls, respectively. In some circumstances, further C-C bond coupling occurs to yield enediolates and eneamidolate metallocycles.

	abstract = {The unique properties of I- allow it to be involved in several different ways in reactions catalyzed by the late transition metals: in the oxidative addition, the migration, and the coupling/reductive elimination steps, as well as in substrate activation. Most steps are accelerated by I- (for example through an increased nucleophilicity of the metal center), but some are retarded, because a coordination site is blocked. The "soft" iodide ligand binds more strongly to soft metals (low oxidation state, electron rich, and polarizable) such as the later and heavier transition metals, than do the other halides, or N- and O-centered ligands. Hence in a catalytic cycle that includes the metal in a formally low oxidation state there will be less tendency for the metal to precipitate ( and be removed from the cycle) in the presence of I- than most other ligands. Iodide is a good nucleophile and is also easily and reversibly oxidized to I-2. In addition, I- can play key roles in purely organic reactions that occur as part of a catalytic cycle. Thus to understand the function of iodide requires careful analysis, since two or sometimes more effects occur in different steps of one single cycle. Each of these topics is illustrated with examples of the influence of iodide from homogeneous catalytic reactions in the literature: methanol carbonylation to acetic acid and related reactions; CO hydrogenation; imine hydrogenation; and C-C and C-N coupling reactions. General features are summarised in the Conclusions.},

	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.

All transitions measured were a-type R-branches, obeying selection rules Delta J=+1, Delta K-a=0, and Delta K-c=+1. Spectra with K-a=0 were measured for 7 isotopomers of Ne-CO, 13 of Kr-CO, and 17 of Xe-CO. Transitions with K-a=1 were measured for Ne-20-(CO)-C-12-O-16 and Kr-84-(CO)-C-12-O-16. Rotational constants and centrifugal distortion constants have been determined for all species, as well as the O-17 quadrupole coupling constants chi(aa) for Kr-84-(CO)-C-13-O-17 and Ne-20-(CO)-C-13-O-17. Effective structural parameters have been calculated from the rotational constants. Results derived from the O-17 quadrupole coupling constants and centrifugal distortion constants indicate that Ne-CO is considerably more flexible than Ar-CO, Kr-CO, or Xe-CO. Failure to observe hyperfine structure due to the Ne-21, Kr-83, and Xe-131 nuclei is discussed in terms of the weak rare gas-CO bonding.

Both orange complexes have been subjected to single-crystal X-ray crystallographic analyses in order to establish their molecular geometries and their intramolecular metrical parameters.

	abstract = {Pure rotational spectra of four different isotopomers of the dimer Ar-CO have been investigated between 8 and 18 GHz using a pulsed beam cavity Fourier transform spectrometer. The spectra confirm that the complex is a prolate near-symmetric rotor with an essentially T-shaped structure, and that it undergoes large amplitude zero-point motion. It is shown that on the average the argon is closer to the oxygen than to the carbon. The transitions measured obey a-type selection rules with DELTAJ = + 1, DELTAK(a) = 0, and DELTAK(c) = + 1. For Ar-40-(CO)-C-13-O-16, transitions have been observed for K(a) = 0 and 1 with lower state J values of 1, 2, and 3. For Ar-40-(CO)-C-13-O-16, and Ar-40-(CO)-C-13-O-18, a similar series was measured, but only for Ka = 0. For Ar-40-(CO)-C-13-O-17, the O-17 quadrupole hyperfine pattern was resolved in the rotational transition J(KaKc) = 2(02)-1(01). Determinations have been made for rotational and centrifugal distortion constants, as well as for the 170 quadrupole coupling constant chi(aa). Effective values have been obtained for the length of the line from the center of mass of the CO subunit to the argon nucleus, and for the angle between this line and the CO bond.},
