AreneCr(CO)2(η2-HSiHPh2) complexes as catalysts for the Si–H bond activation. Hydrolysis of the Si–H bond and dehydrogenative coupling between diphenylsilane and nucleophiles
Abstract
The use of areneCr(CO)2(η2-HSiHPh2) complexes for the efficient catalysis of Si–H bond hydrolysis and, in general, the dehydrogenative coupling of diphenylsilane with nucleophiles is reported; this is the first example of a group VI transition-metal complex acting as a silylation catalyst, involving notably Si–H bond activation through η2-bonding of this group to the metal centre, without oxidative addition.
