资源简介:
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 μ-silyl-bridged dicobalt complexes, [{Co­(IPr)}2(μ-SiH2Hex)4], [{Co­(IPr)}2(μ-SiH2Ph)3(H)3], and [{Co­(IPr)}2(μ-SiHPh2)­(μ-H)2].
