Abstract

Olefin epoxidation by [γ-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.
