Tóm tắt

The Urea-Hydrogen Peroxide complex (UHP) was synthesized from urea and hydrogen peroxide, characterized by FT-IR. This UHP complex could be employed as an oxidizing agent for metal-free oxidation reaction of disulfides to thiosulfinate compounds. This protocol was carried out under very mild conditions at 0oC in CH3CO2H solvent, was efficient and compatible with a range of alkyl, aryl or allyl disulfides to afford direct access to thiosulfinate compounds in very good yields up to 92% and high selectivities.
