The acidic agent (BuSO3H) coated on core-shell Fe3O4 nanomagnetic particles was successfully designed and synthesized. It was characterized and confirmed by different techniques such as FT-IR spectroscopy, scanning electron microscopy vibrating sample magnetometer, X-Ray diffraction, energy dispersive X-ray and Thermogravimetric analysis. The application of Fe3O4@SiO2@(BuSO3H)(3) as an efficient catalyst in the synthesis of propellane derivatives was evaluated by the domino reaction of acenaphthenequinone, malono derivatives, primary amines and b-ketoester derivatives under the solvent-free condition at 60 degrees C.
