  • Mechanistic Study of a Switch in the Regioselectivity of Hydroheteroarylation of Styrene Catalyzed by Bimetallic Ni-Al through CH Activation

    previously reported a highly efficient protocol for bimetallic Ni–Alcatalyzed hydroheteroarylation of styrene with benzimidazole based on CH bond activation. We have now delineated the mechanism of this process, providing a rationale for an observed switch in regioselectivity in the presence of the Lewis acid, AlMe3. The present mechanistic study gives insights for the rational development of catalysts

    A series of cationic gold(I) heteroleptic complexes bearing the pyrazole-derived N-heterocyclic carbene (NHC) FPyr (1,2,3,4,6,7,8,9-octahydropyridazino[1,2-a]indazolin-11-ylidene), and either a 1,3-disubstituted benzimidazole-derived NHC of the type RR′-bimy (3: R = R′ = CHPh2; 4: R = CHPh2, R′ = iPr; 5: R = R′ = CH2Ph; 6: R = R′ = iBu; 7: R = R′ = n-Pr; 8: R = R′ = Et; 9: R = R′ = 2-propenyl) or a non-NHC co-ligand L (10: L = PPh3; 11: L = P(OPh)3; 12: L = DMAP) (DMAP = 4-dimethylaminopyridine) have been synthesized from [AuCl(FPyr)] (1). Complexes 3–12 have been characterized using multinuclei NMR spectroscopies, ESI mass spectrometry, and elemental analysis. X-ray diffraction analyses have been performed on complexes 5, 6, and 9–11. To the best of our knowledge, 11 represents the first gold–NHC complex to bear the P(OPh)3 ligand. The cytotoxic activities of complexes 3–12 have been studied in vitro with the NCI-H1666 non-small cell lung cancer cell line.

  • Synthesis, Structure, and Spectroscopic Properties of Gold(I)−Carbene Complexes
    作者:Harrison M. J. Wang、Charle Y. L. Chen、Ivan J. B. Lin

    A series of gold(I)-carbene complexes of the type [Au(R-2-bimy)L] (R = Et, Me; bimy = benzimidazol-2-ylidene; L = Cl, Br, I, bimy, thiophenolate, phenylacetylide) have been prepared. These carbene complexes are luminous in acetonitrile solution and in the solid state with long lifetimes at room temperature. Multiple emissions have been observed for different R and L. The crystal structure of [Au(Me-2-bimy)Cl] shows a relatively short intermolecular Au-I-Au-I contact of 3.1664(10) Angstrom and an intermolecular ring pi-pi interaction with a ring-ring distance of 3.45 Angstrom. The structure of [Au(Et-2-bimy)Cl], however, shows only intermolecular ring-ring interactions with a distance of 3.53 Angstrom. Crystal structure data suggest that bimy is a high-trans-influence ligand.
  • Facile Synthesis of Silver(I)−Carbene Complexes. Useful Carbene Transfer Agents

    [Ag(Et-2-Bimy)(2)][AgBr2] (1; Et-2-Bimy = diethylbenzimidazol-2-ylidene) was obtained readily from the reaction of [Et-2-BimyH]Br with Ag2O. Compound 2, (Ag(Et-2-Bimy)(2)]PF6, was prepared by the reaction of [Et-2-Bimy]PF6 with Ag2O under basic phase transfer catalysis conditions. Both compounds 1 and 2 are good carbene transfer agents. Thus, Pd(Et-2-Bimy)(2)Cl-2, Au(Et-2-Bimy)Br, and [Au(Et-2-Bimy)(2)]PF6 were obtained in high yields using 1 and 2 as carbene sources. The byproduct AgBr or AgCl can be reused to generate 1 under basic phase transfer catalysis conditions. The crystal structure of compound 1 revealed that linear [Ag(Et-2-Bimy)(2)](+) and [AgBr2](-) groups were associated through a short Ag-I-Ag-I contact (2.956 Angstrom). FAB/mass spectrometry and molar conductivity measurements indicate the existence of ligand-unsupported Ag-I-Ag-I interactions in the gas phase and acetonitrile solution. C-13 NMR studies suggest that the two Bimy ligands in 1 are fluxional in solution.
  • Correlating Thermodynamic and Kinetic Hydricities of Rhenium Hydrides

    notable, however, that even slight perturbations in the steric properties of the Re hydride or the hydride acceptor result in large deviations in the predicted rate of hydride transfer based on thermodynamic driving forces. This indicates that thermodynamic considerations alone cannot be used to predict the rate of hydride transfer, which has implications for catalyst design.
