Fe3O4@Sal@Cu as a Novel Multifunctional Magnetic Nanocatalyst for Clean and Mild Synthesis of 2,3-Dihydro-1H-perimidines

Fe3O4@Sal@Cu magnetic nanoparticles were synthesized and used as a novel multifunctional nanocatalyst for the synthesis of 2,3-dihydro-1H-perimidines by the condensation of naphthalene-1,8-diamine with various aromatic aldehydes under ultrasonication. This efficient methodology has advantages such as good to excellent yields, high purity of the products, reusability of the nanocatalyst, simple reaction conditions, environmental friendliness, and economical chemical procedure.
