α-cleavage during the oxidation of benzazolyl-4-coumarinomethyl sulphides

2-Mercapto benzazoles (2) have been reacted with various 4-bromomethylcoumarins (1) to obtain diheteroaryl sulphides (3). The attempted oxidation of benzoxazolyl sulphides (3) has resulted in α-cleavage of C-S bond leading to the formation of 4-methyl coumarins (5) and benzoxazolone (6). The benzthiazolyl sulphides (4) were found to be oxidised to corresponding sulphones (4). All the newly synthesised sulphides and sulphones have been screened against E. coli, S. aureus, B. subtilis, C. albicans and A. niger.
