| Abstract: | In this paper, a green and facile protocol was described which was efficient for synthesis of benzimidazoles using nano‐Fe3O4 catalyst with continuous bubbling of air as the oxidant in PEG‐400/H2O aqueous system at room temperature. This protocol afforded the target products in good to excellent yields and the catalytic system could be recycled and reused without significant loss of catalytic activity.
