Nafion-H act as a Mild Efficient Reusable Catalyst for the Synthesis of 2-Substituted-1H-Benzimidazoles in solvent free condition


2-Substituted-1H-Benzimidazole derivatives has been prepared successfully by a one pot two component condensation method of varies substituted orthophenylene diamine and varies substituted aldehydes under solvent free condition in presence of Nafion-H catalyst. Microwave heating gave excellent yield of the product within a very short reaction time compared to conventional heating. Reusability and recyclability of the catalyst was explored in the reaction.
