摘要

An efficient synthesis of hexahydro-4-phenylquinoline-3-carbonitriles is described by the four-component condensation reaction of cyclohexanone, ammonium acetate, malononitrile, and aromatic aldehydes using Fe3O4@SiO2-SO3H nanoparticles as a superior and retrievable heterogeneous catalyst under ultrasonic irradiations. The reusability of the catalyst and little catalyst loading, excellent yields, short reaction times, using the sonochemical procedure as a green process and an alternative energy source are some benefits of this method.
