Abstract

An expeditious synthesis of 2-aryl-benzimidazoles by the condensation of o-phenylenediamine with various arylaldehydes is described. This greener protocol is catalyzed by 1,3-Dibromo 5,5-dimethylhydantoin (DBH), and proceeds efficiently in the absence of any organic solvent under thermal condition and microwave irradiation in high yields.
