A Cu(ii)-mediated synthesis of N,N′-diacylhydrazines and 1,3,4-oxadiazoles from aldehyde hydrazones has been developed. This is the first time that the synthesis of N,N′-diacylhydrazines and 1,3,4-oxadiazoles using N,N-dimethylamides as the acylation reagent and O2 in air as the oxidation reagent is reported. These reactions offered several advantages including simple workups, ligand-free inexpensive metal salts as mediators, high yields, and wide scope of substrates.

Anhydride acylation reactions of a variety of substituted arylhydrazines under mild conditions led to controlled formation of the acid phenylhydrazides I (Table I).The procedures were tallored to the particular state of the starting arylhydrazine.Second-s
