Abstract

We report the synthesis of benzimidazoles using Boron trichloride as an efficient catalyst. One-pot synthesis of 2- substituted benzimidazole derivatives from o-phenylenediamine and a variety of aldehydes were developed under mild reaction conditions. On completion of reaction the products were characterized by IR, NMR and Mass Spectra. These methods are more convenient and reactions can be carried out in higher yield.
