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

Abstract

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%).
