New Bis-1,3,4-Thiadiazoles Based on Fumaric Acid: Preparation, Structure Elucidation, Antibacterial Activities, and Quantum-Chemical Studies
{{output}}
New bis-1,3,4-thiadiazoles (1-7) were obtained by the reaction of fumaric acid and N-(alkyl/aryl/cyclic)thiosemicarbazides in the presence of phosphorous oxychloride. The structures of all compounds were elucidated by FT-IR, 1H NMR, and 13C NMR and elemental m... ...
