Abstract

Green chemistry, a novel and simple method have been developed for the synthesis of some a new series of complexes of 4‐((3‐Formyl‐4‐hydroxyphenyl) diazenyl) ‐N‐(4‐methyloxazol‐2‐yl) benzenesulfonamide with the metal salts of Cu(II), Ni(II), Zn(II), and Ag(I)using a microwave irradiation. The structure of these sulfonamide compounds has been investigated by using elemental analysis, FT-IR, 1H NMR, UV-Vis spectrometric methods, magnetic susceptibility, conductivity measurements and thermal studies. These compounds were screened for in-vitro antibacterial activity against staphylococcus aureus and Streptococcus mutans (Gram positive bacteria), Escherichia coli, Pseudomonas aeruginosa and klebsiella (Gram negative bacteria) and for in-vitro antifungal activity against Candida albicans. The results of the antimicrobial activity studies showed that metal complexes have higher activities than parent ligand. Also, ligand displayed potent antioxidant activity.
