Synthesis and Antibacterial Activities of 4‐Amino‐3‐(1‐aryl‐5‐methyl‐1,2,3‐triazol‐4‐yl) ‐5‐mercapto‐1, 2,4‐triazoles/2‐ Amino‐5‐(1‐aryl‐5‐methyl‐1,2,3‐triazol‐4‐yl)‐1,3,4‐thiadiazoles and Their Derivatives

Treatment of 4‐amino‐3‐(1‐aryl‐5‐methyl‐1,2,3‐triazol‐4‐yl)‐5‐mercapto‐1, 2,4‐triazoles/2‐amino‐5‐(1‐aryl‐5‐methyl‐1,2, 3‐triazol‐4‐yl)‐1,3,4‐thiadiazoles with benzaldehyde, acetone and ω‐bromoacetophenone was tested and compared. The title compounds Schiff bases, amides, imidazolo[2, 1‐ b ]‐1,3,4‐thiadiazoles and 7 H‐s ‐triazolo [3, 4‐ b ]‐1, 3, 4‐thiadiazines have been confirmed by elemental analyses, 1 H NMR, IR and MS spectra. All the compounds have also been screened for their antibacterial activities against B. subtilis, S. aureus and E. coli .
