## Abstract __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
