study, a novel series of 6-oxopyridazinyl benzazoles and 3, 6-dioxopyridazinyl benzazoles were prepared from the starting compounds, 2-hydrazinobenzimidazole, 2-hydrazinobenzothiazole and 2-hydrazinobenzoxazole by reaction with butyric acid derivatives and cyclic anhydrides respectively. The structures of the new compounds were confirmed by elemental analysis as well as 1H NMR, IR and MS data. Some of the
