, a study on the influence of azole moiety on the capability for intramolecular cyclization and its direction was carried out. It was found that for 4-aryl/alkyl-thiosemicabazides with triazole, imidazole, or pyrrole moiety at N-1 nitrogen atom possible products were only s-triazoles, both in alkaline and acidic medium. Successful dehydrocyclization of 1-azolil-4-aryl/alkyl-thiosemicarbazides leading
