Hydrosilylation catalyzed by a high-valent nitridoruthenium (VI) compound,[RuN (saldach)(CH3OH)]+[ClO4]−(1, where saldach is the dianion of racemic N, N′-cyclohexan- diyl-bis (salicylideneimine)) is described. Using phenylsilane as reductant, a variety of unsaturated organic substrates, including aldehydes, ketones, and imines, are effectively reduced to alcohols and amines, respectively, accompanied by the redistribution of ...
