在乙睛溶剂中考察了一系列杂多化合物和过氧化氢水溶液催化的各种缺电子的α,β-不饱和羰基化合物的环氧化反应.在所研究的杂多化合物中,二缺位的[γ-SiW10(H2O)2O34](Bu4N)4显示出了最高的活性.
The epoxidation of various electron-deficient α, β-unsaturated carbonyl compounds catalyzed by a series of heteropoly compounds and aqueous hydrogen peroxide was investigated in acetonitrile solvent. Among the heteropoly compounds studied, Of [γ-SiW10 (H2O) 2O34] (Bu4N) 4 showed the highest activity.
