摘要：

A cobalt dialkyl with an N-heterocyclic carbene [Co(CH2SiMe3)(2)(IPr)] (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazole-2-ylidene) underwent successive Si-H bond cleavage of hydrosilanes. The reaction paths were highly dependent on the bulkiness of the hydrosilanes, which led to the formation of various mu-silyl-bridged dicobalt complexes, [{Co(IPr)}(2)(mu-SiH(2)Hex)(4)], [{Co(IPr)}(2)(mu-SiH2Ph)(3)(H)(3)], and [{Co(IPr)}(2)(mu-SiHPh2)(mu-H)(2)].
