l-Arginine complex of copper on modified core–shell magnetic nanoparticles as reusable and organic–inorganic hybrid nanocatalyst for the chemoselective oxidation of organosulfur compounds

In this paper, we report the fabrication and characterization of a stable heterogeneous nanostructure catalyst of copper immobilized on Fe3O4@SiO2@l-Arginine, for the oxidation of sulfdes and oxidative coupling of thiols. The prepared nanocatalyst has been characterized by diferent techniques such as FTIR, XRD, SEM, TEM and TGA. These nanoparticles were the efective catalyst for selective oxidation of sulfdes and oxidative coupling of thiols using 30% H2O2. The suggested method ofers several prominent advantages such as mild condition, use of magnetically reusable catalyst, simple workup procedure, good to high yields of products and great selectivity.
