An easy, direct and room temperature silicon-carbon bond activation is reported. The reaction of [RhCl(coe)2]2 with the silane Si(Me)2(o-C6H4SMe)2 in the presence of an halide extractor provokes a Si-CH3 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)]2 or [RhCl(nbd)]2, the Si-CH3 bond activation does not occur.

Si-C(sp3)通过Rh(i)中心的氧化加成键活化。

据报道,容易,直接和在室温下进行硅-碳键活化。在卤化物萃取器的存在下,[RhCl(coe)2] 2与硅烷Si(Me)2(o-C6H4SMe)2的反应引起Si-CH3键裂解,产生阳离子甲硅烷基-甲基-Rh(iii) 。相反,如果使用Rh(i)双烯烃二聚体[RhCl(cod)] 2或[RhCl(nbd)] 2进行反应,则不会发生Si-CH3键活化。
