A simple and efficient catalytic system including 3-methyl-4-oxa-5-azahomoadamantane and FeCl3 for aerobicoxidative synthesis of benzimidazoles from primaryamines and o -phenylenediamine is presented. This process uses O2 as economic and green oxidant and water as green solvent, tolerates a wide range of substrates, and can afford the target products in moderate to excellent yields.
