Abstract :A new synthetic approach has been applied to obtain a compound 3,4-diamino-1H-1,2,4-triazole-5insert ignore into journalissuearticles values(4H);-thione insert ignore into journalissuearticles values(2); by using 5-amino-1,3,4-thiadiazole-2-sulfonamide insert ignore into journalissuearticles values(1); and hydrazine hydrate as starting materials. New Schiff bases insert ignore into journalissuearticles values(3a-d); are obtained by the reaction of the compound 3,4-diamino-1H-1,2,4-triazole-5insert ignore into journalissuearticles values(4H);-thione insert ignore into journalissuearticles values(2); and varied aldehydes. The structures of the new compounds were characterized by spectral insert ignore into journalissuearticles values(IR, 1H and 13C NMR); and elemental analysis.
Keywords : Thione, Schiff base, Sulfonamide, Triazole, Hydrazine hydrate
