Abstract: The synthesis and catalysis of epoxidaton for olefin of a-and β-K6H4[SiW9O37 Mn3·(H2O)3]·xH2O are reported.The heteropolyacid salts have an ability to catalyze the epoxidation of olefin by PhIO,and the catalytic activity of them is probably related to the fact that the substituted Mn(II)can be oxidized to a higher oxidation state and the compound with a higher oxidation state has an oxidation property.

Key words: Trisubstituted Keggin heteropolyanion, Transfer agent of oxygen atom, Epoxidation of olefin
