REACTION OF N-AMINOBENZIMIDAZOLIUM CATIONS WITH AROMATIC ALDEHYDES. SYNTHESIS OF 2,4-DIARYL-as-TRIAZINOBENZIMIDAZOLES

Article abstract of DOI:10.1007/BF00514995

On heating with aromatic or heteroaromatic aldehydes in polar aprotic solvents, 1-amino-3-alkylbenzimidazolium salts form 2,4-diaryl derivatives of a new heterocyclic system of as-triazino<1,6-a>benzimidazole.
