An easy, direct and room temperature silicon-carbon bond activation is reported. The reaction of [RhCl(coe)] with the silane Si(Me)(o-CHSMe) in the presence of an halide extractor provokes a Si-CH bond cleavage yielding a cationic silyl-methyl-Rh(iii). In contrast, if the reaction is performed using the Rh(i) bis-alkene dimers, [RhCl(cod)] or [RhCl(nbd)], the Si-CH bond activation does not occur.
报道了一种简单、直接且在室温下的硅-碳键活化反应。在卤化物萃取剂存在下，[RhCl(coe)]与硅烷Si(Me)(o-CHSMe)反应会引发Si-CH键断裂，生成阳离子型甲硅烷基-甲基-Rh(iii)。相比之下，如果使用Rh(i)双烯烃二聚体[RhCl(cod)]或[RhCl(nbd)]进行该反应，则不会发生Si-CH键活化。
