DMP(1,1,1-Triacetoxy-1,1-dihydro-1,2-benziodoxol-3(1H)-one):A novel catalyst for synthesis of 2-substituted benzimidazoles derivatives

Various 2-arylbenzimidazoles were synthesized from o-phenylenediamine and aldehydes via one-step process using DMP （Dess-Martin-periodinane） reagent as an oxidant. The method was proved to be simple, convenient and the products were isolated with good yields （80-90%）. ？2009 Charansingh H. Gill. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
