Chemistry of Heterocyclic Compounds Aims and scope

Abstract

2-Phenylbenzimidazole and its mono and diamino derivatives were synthesized in yields up to 85% by cyclodehydration of o-aminobenzanilides in hydrochloric or sulfuric acid. The IR spectra of the compounds obtained were studied, the principal bands of the stretching and deformation vibrations of the NH and NH2 groups were assigned, and the presence of associates with a hydrogen bond was established.
