Abstract

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 = 1-butyl-3-methylimidazolium) using aqueous H2O2 (35%) as oxidant. The products were obtained in high yields. Compared to the analogous reactions in organic solvents, this system can be recycled without significant loss of activity and selectivity. Additionally, the reaction mechanism was examined by IR, Raman and NMR spectroscopy. Based on these examinations, it appears that the crucial step during the oxidation procedure is the formation of a hydrogen bond between the ionic liquid and the oxidant.
