摘要：

Four-legged piano stool complexes (eta(6)-arene)Ru(H)(2)(SiEt(3))(2) and (eta(5)-C(5)Me(5))Rh(H)(2)(SiEt(3))(2) catalyse the transfer dehydrogenative coupling of Et(3)SiH in the presence of a hydrogen acceptor such as tert-butylethyiene to yield the carbosilane dimer, HSiEt(2)CHMeSiEt(3), and 2,2-dimethylbutane by a mechanism involving an intermediate eta(2)-silene complex, L(n)M(Et(2)Si=CHMe), generated by beta-hydrogen elimination from a silyl group.
