Right combination: Imidazolium perrhenate ionic liquids (ILs) are effective catalysts for the epoxidation of unfunctionalized olefins using hydrogen peroxide as oxidant. The catalytic activity strongly depends on the IL solubility in aqueous H2O2, which is regulated by the nature of the cation. The IL catalysts significantly enhance the solubility of olefins into the aqueous phase, allowing for the reaction to take phase in water.
