Preparation of Amidoalkyl-2-Naphthols by using of the Magnetic Ionic Liquids as catalyst

Acidic Ionic Liquid-functionalized magnetic nanoparticles (AIL-MNPs) are synthesized and used asefficient heterogeneous solid acid catalyst for the condensation of aromatic aldehydes with 2-naphthol and amides (or carbamates) via three-component reactions to synthesis of Amidoalkyl-2-Naphthols under solvent-free conditions at 80 oC. Recovery of the catalyst was easily achieved bymagnetic decantation.
