The reaction of 5-amino-1-aryl-1,2,3-triazole-4-carbothioamides with sulfonyl chlorides and acetyl and benzoyl chlorides is accompanied by the Dimroth rearrangement and proceeds regiospecifically with the formation of 5-arylamino-2-sulfonyl(acyl)-1,2,3-triazoles. The reaction mechanism was confirmed by the synthesis of the target products via the reaction of 5-arylamino-1,2,3-triazole-4-carbothioamides with sulfonyl and acyl chlorides.
