1,3‐Dibromo 5,5‐dimethylhydantoin (DBH)‐Catalyzed Solvent‐Free Synthesis of 2‐arylbenzimidazoles under Microwave Irradiation

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...

Description
Summary: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.
