One-pot synthesis of benzimidazoles in water in the presence of SiO 2-OPO3H

Mirjalili,Bamoniri,Rahimi Kazerouni

, p. 35 - 40 (2014/05/06)

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.
