Nano-[Fe3O4@SiO2@RNHMe2][HSO4] (NFSRNH), as an effectual and magnetically recyclable catalyst, promoted the solvent-free production of 1-amidoalkyl-2-naphthols through the multi-component reaction of aldehydes, 2-naphthol and primary amides. This method has the advantages of high yield, mild reaction conditions, environmentally benign methodology and short reaction time. Given the increasing levels of interest in green chemistry, the recyclability and reusability of the catalyst have been evaluated.
