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.
[Pw_ (11) O_ (39) M] ~ (n -), [P_2W_ (17) O_ (61) M] ~ (41) were reported by Hill ~ [1], Finke ~ [2] and Neumann ~ [3] The catalytic activity of epoxidation of olefins is similar to that of the [SiW 11 O 39] Ru] 5- (5-) .The trisubstituted Keggin heteropolyanions have similar properties.In this paper, we report for the first time that α- and β- The synthesis of K_6H_4 [SiW_9O_ (37) Mn_3 (H_2O) _3] · xH_2O and its transfer of oxygen atoms provide a new manganese-containing heteropolyanion for the study of heteropolyacid salt catalysis.
