Abstract: In the presented work, Fe3O4 bonded nicotinic acid-sulfonic acid chloride (Fe3O4@nicotinic acid @sulfonic acid chloride), as a magnetic reusable catalyst, was prepared by a simple procedure. The identification of Fe3O4@nicotinic acid @sulfonic acid chloride was studied by Fourier transform infrared spectroscopy, X-ray diffraction, thermal gravimetric analysis, scanning electron microscopy, energy dispersive X-ray analysis and vibrating sample magnetometry. Fe3O4@nicotinic acid @sulfonic acid chloride was employed as an efficient and heterogeneous catalyst for the one-pot synthesis of some 1-carbamato-alkyl-2-naphthol derivatives in high yields under solvent-free conditions. Simple work up, high yields, short reaction times and easy recovery of catalyst are some advantages of this work.
