Abstract
Fe3O4-CNTs composites are synthesized using simple chemical coprecipitation which is confirmed with XRD, VSM, TEM and EDS. Fe3O4-CNTs as a magnetically active catalyst catalyze one-pot multicomponent condensation of β-naphthol with aromatic and aliphatic aldehydes and amide derivatives under solvent-free conditions and microwave-irradiation to afford the corresponding amidoalkyl naphthols in excellent yields. This catalyst provides clean conversion; greater selectivity and easy workup make this protocol practical and economically attractive.
