A direct and efficient method for constructing N,N-disubstituted hydrazines via a palladium-catalyzed allylic substitution of allyl acetates with arylhydrazines as nucleophiles has been developed. This method is highly selective in terms of both chemo- and regio-selectivity and is carried out under an open-air system with the use of the DPPPy phosphine ligand. Additionally, this reaction is compatible with a wide variety of substrates, including those bearing reactive groups such as Cl, Br, and I, to afford various N1-allylation products in moderate to good yields under simple and mild reaction conditions.
