A novel and simple method for the selectively oxidation of sulfides to sulfoxides and oxidation of disulfides to thiosulfonates in the presence of t-butyl hydroperoxide (TBHP) has been established. The oxidation system has the advantages of avoiding the use of any catalyst and additive, possessing a broad substrate scope and high efficiency. Desired sulfoxides and thiosulfonates products were obtained in moderate to good yields. Furthermore, a plausible mechanism of the reaction is proposed. The results of control experiments revealed that a radical pathway was involved in this oxidation.
