One-pot synthesis of 2-substituted benzimidazoles catalyzed by anhydrous FePO4

Abstract

Anhydrous FePO4 has been employed as a catalyst for efficient synthesis of 2-substituted benzimidazoles. Simple and convenient procedure, easy purification and shorter reaction time are the advantages of this method resulting in several known and three new compounds.
