摘要
Hill~[1],Finke~[2]和Neumann~[3]曾分别报道[Pw_(11)O_(39)M]^(n-)、[P_2W_(17)O_(61)M]^(n-)和[SiW_(11)O_(39)Ru]^(5-)具有催化烯烃环氧化反应的性质,三取代的Keggin杂多阴离子有相似的性质.本文首次报道α-和β-K_6H_4[SiW_9O_(37)Mn_3(H_2O)_3]·xH_2O的合成及其转移氧原子的性质,为研究杂多酸盐的催化提供了一个新的含锰杂多阴离子.
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.
