Hydrogen peroxide was generated in room temperature ionic liquids by electrolysis, which was then used for the epoxidation of lipophilic alkenes under a carbon dioxide-saturated environment and in the presence of catalytic amount of manganese salt.13C NMR showed that the active peroxymonocarbonate (HCO4-) was generated from the mixture of H2O2, CO2, and water in the ionic liquids. Most lipophilic alkenes were selectively epoxidized within 4-5 h. The ionic liquids can be recovered and reused without any deterioration in the performance.
