Abstract:

In this study, an efficient method for the synthesis of 2-Aryl Benzimidazole derivativeshas been developed. The synthesis was performed by condensation aromatic benzaldehydes and 1.2 phenylenediamin using [bmim][FeCl4]/MCM-41 as a heterogeneous catalyst under reflux conditions and at 60 ̊C. The advantages of this method are easy work-up procedure, clean and neutral reaction conditions. The separation and reuse of the catalyst were simple and could be reused without a significant loss of catalytic activity. Moreover, the products were achieved in good yields (70-83%).
