Abstract
Borohydride hydrogenations using agents of the formula M[RR'R'BH] wherein M is a metal and R, R', and R' are each organic groups, at least one of them being a secondary or tertiary alkyl group, are described herein. These compounds are active hydrogenating agents which are particularly useful because they permit steric control of the hydrogenation of carbonyl groups, they permit selective hydrogenation of functional groups or, where one of the R groups is optically active, they permit stereoselective hydrogenation.
