A series of novel Brnsted acidic organic perrhenates were applied as catalysts for sulfide oxidations using 30% H2O2 as oxidant. The structures and thermal stability data of the catalysts were characterized by FT-IR, NMR and TGA. Meanwhile, the effect of various solvents, the dosage of H2O2 and catalyst, temperature and the reaction time on the catalytic performance was studied in details. The results indicate that the selectivity and yield of sulfoxide can reach up to 95% under the optimal conditions, in which the dosage of catalyst is 0.03 mol, the dosage of H2O2 is 2.4 mmol, 40 ℃ and 90 min.
