Reaction of a 1,2-disilylene with CO under ambient conditions leads to a bis(silylene), the five-membered heterocycle of which represents the first silicon analogue of an “abnormal” N-heterocyclic carbene (see picture). Reactions of the bis(silylene) with transitionmetal carbonyls lead to different outcomes, including a chelate complex of the Mo(CO)4 fragment.
在环境条件下,1,2-二甲硅烷基与 CO 反应生成双(甲硅烷基),其五元杂环代表“异常”N-杂环卡宾的第一个硅类似物(见图)。双(甲硅烷基)与过渡金属羰基化合物的反应导致不同的结果,包括 Mo(CO) 4片段的螯合物。

Abstract Thermalrearrangement of the 1,2-bis(silylene), [(4-ButPh)C(NDip)2}Si−]2 (Dip = 2,6-diisopropylphenyl, leads to the silyl-silylene, (4-ButPh)C(NDip)2}Si−Si(H) N(Dip)C(=NDip)(4-ButPh-H)}, via an intramolecular C−H activation reaction. The X-ray crystal structure, and limited spectroscopic data, for the compound are reported. The structure of the silyl-silylene incorporates an exocyclic imine
