Abstract A convenient method for the reduction of N,N-dimethylhydrazones using amine borane complexes generated in situ is described. It was found that primary amine borane complexes performed exceedingly well at reducing N,N-dimethylhydrazones in as little as 1.1 equivalents, furnishing the corresponding air-sensitive hydrazine products in excellent yields.

N,N-Dimethylhydrazones of aldehydes react with hydrogen peroxide at –50 °C in the presence of catalytic amounts of methyltrioxorhenium (MTO) to give in high yield the corresponding nitriles and N-methylene-N-methyl N-oxide.
