Rapid synthesis of 2-amino maleonitrile Schiff bases in aqueous media catalyzed by cerium(IV) ammonium nitrate (CAN) and a new method for the one-pot preparation of their dicyano imidazoles (DCI)

AbstractStarting from readily available 2-naphthol, aldehydes, aryl and alkylamines, a variety of Betti bases were efficiently synthesized utilizing a catalytic amount of cerium (IV) ammonium nitrate (CAN) at room temperature. This protocol has advantages of high yield, mild reaction conditions, no environmental pollution, diversity of reactants and simple work up procedure.
