  摘要：

  The N-heterocyclic carbene (NHC) nickel complexes [(L)Ni(NHC)][BAr4F] (Ar-F = 3,5-bis(trifluoromethyl)-phenyl; L = allyl (1), methylallyl (2); NHC = 1-(2-picolyl)-3-methylimidazol-2-ylidene (a), 1-(2-picolyl)-3-isopropylimidazol-2-ylidene (b), 1-(2-picolyl)-3-n-butylimidazol-2-ylidene (c), 1-(2-picolyl)-3-phenylimidazol-2-ylidene (d), 1-(2-picolyl)-3-methylbenzoimidazol-2-ylidene (e), 1-(2-picolyl)-4,5-dichloro-3-methylimidazol-2-ylidene (0) have been obtained in high yields and characterized by NMR spectroscopy. Furthermore, Id was unambiguously characterized by single-crystal X-ray crystallography. Complexes 1a-f/2a-f have shown catalytic activity toward dimerization and hydrosilylation of styrenes. In particular, 1a proved to be the most efficient catalyst in the dimerization of styrene derivatives in the absence of cocatalyst. Also, complexes 1a,d showed high selectivity and moderate to good yields in hydrosilylation reactions.
