Fast catalytic epoxidation with H(2)O(2) and [gamma-SiW(10)O(36)(PhPO)(2)](4-) in ionic liquids under microwave irradiation.
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.
