Abstract
3,5-Disubstituted 1-methyl-1H-1,2,4-triazoles and -pyrazoles were obtained in good to moderate yields by the reaction of N-methyl-N-(phenylsulfonyl)benzohydrazonoyl chloride with nitriles and with acetylenes in the presence of aluminum chloride. The triazoles were also formed by the reaction of acid chlorides with N-methyl-N-(phenylsulfonyl)benzamidrazone which was generated from the hydrazonoyl chloride and ammonia.
