Trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane as a novel and efficient reagent for selective sulfoxidation of sulfides under catalyst-free condition

Application of trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane as an efficient and high-oxygen content reagent in selective oxidation of sulfides into sulfoxides has been successfully explored. The reactions proceeded under mild and catalyst-free conditions in dichloromethane at room temperature to provide the sulfoxides in excellent yields without any significant over-oxidation to sulfones.
