Practical, ecofriendly, and chemoselective method for the synthesis of 2-aryl-1-arylmethyl-1H-benzimidazoles using amberlite IR-120 as a reusable heterogeneous catalyst in aqueous media

Abstract

A simple, efficient, and environmentally benign method has been developed for the exclusive formation of biologically significant 2-aryl-1-arylmethyl-1H- benzimidazoles under the heterogeneous catalysis of Amberlite IR-120 in aqueous media in excellent yields. The catalyst is recyclable without loss of activity. Copyright © Taylor & Francis Group, LLC.
