One-Pot Synthesis of Benzimidazoles in Water in the Presence of SiO2–OPO3H

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Silica-bound phosphoric acid (SiO2–OPO3H), as an eco-friendly, reusable, and heterogeneous catalyst, was applied for synthesis of 2-substituted benzimidazoles in water at 70°C. Very short reaction times, clean work-up, and high yields are among the advantages of this protocol.
