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

Received05 Nov 2011
Accepted15 Jan 2012


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.
