[GRAPHICS]
Olefin epoxidation by [gamma-SiW10O36(PhPO)(2)](4-) and H2O2 occurs in hydrophobic ionic liquids (ILs), with yields and selectivity up to > 99%. The catalytic IL phase is recyclable. Under MW irradiation the reaction occurs with up to 200 turnovers per minute. Simultaneous cooling is instrumental for quantitative H2O2 conversion.
