| Abstract: | The epoxidation of a variety of electron-deficient α, β-unsaturated carbonyl compounds has been studied using a series of heteropoly compounds and aqueous hydrogen peroxide in acetonitrile. Among the heteropoly compounds investigated, a divacant lacunary γ-SiW10(H2O)2O34](Bu4N)4 showed the highest catalytic performance for the epoxidation ofα, β-unsaturated carbonyl compounds. |
