, p. 282 - 287 (2007/10/03)
Reactions of bis-benzalethylenediamine (1), N,N'-bis(aryl)- and N,N'-bis(cyclohexyl)ethane-1,2-diylidenediamines as well as N,N'-bis(aryl)benzene-1,4-diyldimethylidenediamines 2 with benzo- and naphthoquinones as well as α,β-unsaturated ketones such as 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ); 2,3,5,6-tetrachloro-1,4-benzoquinone (CHl-p); 3,4,5,6-tetrachloro-1,2-benzoquinone (CHl-o); 2,3-dichloro-1,4-naphthoquinone (DCNQ); 2,3-dicyano- l,4-naphthoquinone (DCNQ) and dicyanomethyleneindane-1,3-dione (CNIND) afforded quinoxaline, pyrazinoquinoxaline, imidazolidine, indole and carbazole derivatives as well as arylaminobenzo-, and napthoquinones.
Studies with arylaminomethylbenzimidazolethiols: Novel synthesis of 1,3-diazepino- and 1,2,4-triazepino[1,2-a] benzimidazole derivatives
Hassan, Alaa A.
, p. 231 - 236 (2007/10/03)
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.
