Abstract Addition of substituted benzyl bromides to dialkylazodicarboxylates under aqueous zinc-mediated addition conditions occurs readily to afford monobenzylated hydrazides in good to excellent yields. The reaction is tolerant of a variety of substituents on the benzyl bromide ring. Several dialkylazodicarboxylates were successfully tested under the reaction conditions. The limitations of the
