Catalytic performance of Keplerate polyoxomolybdates in green epoxidation of alkenes with hydrogen peroxide

The catalytic activity of three Keplerate POM, Mo₇₂M₃₀ (V, Cr and Fe), in the green epoxidation of alkenes with 30% H₂O₂ in water are investigated. Mo₇₂Cr₃₀ was shown the highest catalytic activity and efficiently reused without any loss of activity.
