ABSTRACT

Synthesis of phenyl (5-substituted phenyl-1,3,4-thiadiazol-2-yl) methanediamine (TDZ-A to TDZ-C), reaction between aryl aldehydes and Thiosemicarbazide yielded thiosemicarbazone. Thiosemicarbazone in the presence of citric acid and sodium acetate gives 2-amino-5-aryl -1,3,4-thiadiazole, which is treated with aniline in the presence of formaldehyde to obtained targeted compounds phenyl(5-substituted phenyl-1,3,4-thiadiazol-2-yl)methanediamine. The synthesized Thiadiazoles have been characterized on the basis of analytical spectral data. The resulted compounds were screened for their antibacterial, antifungal and antioxidant activities.

Keywords: Aromatic aldehydes, Thiosemicarbazide, Formaldehyde, Antioxidant activity, Antibacterial activity, Antifungal activity.
