This paper describes the synthesis and characterization of copper-integrated magnetic nanoparticles (Fe3O4@silica-Lys-Cu(PPh3)I) with a size less than 16 nm. The complex was adequately characterized by thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), energy dispersive X-ray analysis (EDX), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and a vibrating sample magnetometer, (VSM). Using the Chan-Lam coupling method, the catalytic performance of copper integrated magnetic nanoparticles (Fe3O4@silica-Lys-Cu(PPh3)I) was investigated in the preparation of bioactive N-aryl sulfonamides from a variety of aryl boronic acids and sulfonyl azides in ethanol. The key advantages of present method are magnetically separable catalyst by applying external magnet and use of green solvent. The reusability studies exhibit that complex can be reused up to eight consecutive times without material reduction in catalytic activity.
