antimicrobial agents. The chemistry involves the condensation of sulfanilamide derivatives 1 with trifluoroaceticanhydride to give N-di(trifluoroacetyl)sulfonamides 2 which upon reaction with hydrazine hydrate afforded the corresponding triazole derivatives 3. Reaction of triazole derivative 3a with isocyanates and isothiocyanates gave the corresponding ureas 4 and thioureas 5. Cyclization of thiourea derivatives
