Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
N-Benzoylhydrazones (=N'-alkylidene-substituted benzohydrazides) 1 are allylated efficiently by reaction with allyl bromide (2) in the presence of Zn in aqueous NH(4)Cl solution. The products 3 are formed in excellent yields (85-94%) within 35-50 min (Scheme, Table).
