Abstract
Unlike other alkylamines, benzylamines upon reaction with a nitrosoarene undergo oxidation
to the corresponding imines. A direct amination of benzylamines, which was difficult
to achieve due to its facile oxidation, to the corresponding hydrazones is reported.
A wide variety of benzylamines and N-heterocycles were reacted with nitrosoarenes
to provide structurally diverse hydrazones and hydrazides, respectively. Moreover,
the direct N-amination reaction was applied to the one-pot synthesis of triazoles.
Key words
