General procedure: Fe3O4MCM-41Ni-P2C (10 mg) was added to a mixture of thiol (1 mmol) and 33% H2O2 (0.4 mL) in ethanol (3 mL). The resulting reaction mixture was stirred for the specified time at room temperature (the progress of reaction was monitored by TLC). After completion of the reaction, the catalyst was separated by an external magnet and the product was washed with ethyl acetate. Then organic layer was dried over anhydrous Na2SO4 (1.5 g). Finally, the organic solvent was removed by simple evaporation and disulfides were obtained in very high isolated yields.
