A series of perrhenate ionic liquids(PILs)were synthesized and used as efficient catalyst for the oxidation of sulfides to sulfones with aqueous hydrogen peroxide under mild conditions.Various sulfone
A highly selective and efficient oxidation of sulfides to sulfoxides is presented.The reactions were carried out at room temperature in the absence of a catalyst in the ionic liquid [Bmim][BF4](Bmim =
