A fast catalytic epoxidation of both terminal and internal double bonds was promoted by the regioselective tetraprotonation of the polyoxometalate γ-[(SiO4)W10O32]8−, which leads to the localization of two water molecules on the reactive lacunary site. This mechanism was supported by evidence from kinetic, spectroscopic, and computational studies.

Abstract
A fast catalytic epoxidation of both terminal and internal double bonds was promoted by the regioselective tetraprotonation of the polyoxometalate γ-[(SiO4)W10O32]8−, which leads to the localization of two water molecules on the reactive lacunary site. This mechanism was supported by evidence from kinetic, spectroscopic, and computational studies.
