SOME NEW 3<i>H</i>-BENZO[<i>b</i>]THIOPHENE[3,2-<i>e</i>]BENZIMIDAZOLE DERIVATIVES

Abstract

Fusing 1,2-diaminodibenzothiophene dihydrochloride with urea and thiourea led to the formation of benzo[b]thiophene[3,2-e]benzimidazolone and benzo[b]thiophene[3,2-e]benzimidazolethione. 3H-Benzo-[b]thiophene[3,2-e]benzimidazole was used to obtain 3-ethylbenzo[b]thiophene[3,2-e]benzimidazole, 3-ethylbenzo[b]thiophene[3,2-e]benzimidazole-2-thione, and 3-ethylbenzo[b]thiophene[3,2‑e]benz-imidazole-2-sulfonic acid.
