Abstract

Lewis base promoted direct reductive hydrazination enables a straightforward and facile synthesis of 1,1-disubstituted hydrazines with very good yields. Under the catalysis of hexamethylphosphoramide (HMPA) and N,N-dimethylacetamide (DMAc), respectively, various ketones and aldehydes reacted with phenylhdrazines.
