Abstract

4H-Imidazo[4,5-e][2,1,3]benzothiadiazol-5(6H)-one (3) has been prepared by the condensation of 4,5-diamino-2,1,3-benzothiadiazol (1) with urea. 4,5-Diamino-2,1,3-benzothiadiazole (1) was also fused with thiourea to get the 5-mercapto-4H-imidazo[4,5-e][2,1,3]benzothiadiazole (2). Reactions on the compound (3) have been investigated.
