Abstract
3-Oxo-2-arylhydrazonobutanenitriles react with hydroxylamine hydrochloride in ethanolic sodium acetate to yield either amidoximes or isoxazolamines depending on the nature of the substituent. The amidoximes cyclise in refluxing DMF containing piperidine to form 2-aryl-1,2,3-triazol-5-amines. The isoxazolamines rearranged into 1,2,3-triazolamines on refluxing in DMF. Amidoxime
