Magnetic Ionic Liquids; Efficient Catalysts for Preparation of Amidoalkyl-2-Naphthols

Acidic Ionic Liquid-functionalized magnetic nanoparticles (AIL-MNPs) are synthesized and used as efficient 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 by magnetic decantation.
