ω-Chloroisonitrosoacetophenone was treated with ethylenic and acetylenic dipolarophiles to afford 3-benzoylisoxazolinines and -isoxazoles, respectively. With m-nitrobenzaldoxime or m-nitrobenzonitrile, it yielded 3-benzoyl-5-(m-nitrophenyl)-1,2,4-oxadiazole. The phenylhydrazones of the 3-benzoylisoxazole and -oxodiazole thus produced were converted to the corresponding 1,2,3-triazoles thermally or
