Studies with arylaminomethylbenzimidazolethiols: Novel synthesis of 1,3-diazepino- and 1,2,4-triazepino[1,2-a] benzimidazole derivatives

Article abstract of DOI:10.1080/10426509608046393

The reaction of 3-(p-substituted arylaminomethyl)benzimidazole-2-thiols 1a,b with tetracyanoethylene (TCNE) afforded 1,3-diazepino[1,2-a]benzimidazole derivatives 8. 2-Hydrazinobenzimidazole 2 reacted with TCNE and dicyanomethyleneindane-1,3-dione (CNIND) to form 1,2,4-triazepino[1,2-a]benzimidazole derivatives 17 and 18.
