Abstract
Aldehydes, ketones, esters and lactones may be reduced using a reductant system consisting of a silane derivative and a metal hydride to give good yields of the corresponding alcohols. The reductant system used in the method enables preferential reduction of the carbonyl function. In one embodiment, the reductant system consists of polymethylhydroxysilane and a metal hydride, the hydride being prepared in situ or ex situ from a metal salt or complex by means of a reaction with a reducing agent.
