Abstract

Highly efficient transfer hydrogenations of imines were realized with as low as 0.1 mol% of B(C6F5)3 by using Hantzsch esters as a hydrogen source, furnishing a variety of amines in 80-99% yields. For the asymmetric transfer hydrogenations, up to 38% ee was obtained with chiral diene-derived boron Lewis acids.
