Abstract

Reactions of acid chlorides of 1,2,4-oxadiazole-3-carbohydroximic acids with hydrazines lead to the formation of unstable hydrazidoximes, which readily undergo rearrangement to hydrazinofurazans. In the reaction with 4-nitrophenylhydrazine, the parallel reaction, leading to the formation of the amidrazone which undergoes rearrangement to the diaminotriazole, also proceeds simultaneously
