[XOp]n- (X = As, HAs, MeAs, P, HP, etc.) has a marked effect on the stoichiometric and regioselective epoxidation of (R)-(+)-limonene to 1,2-epoxide at ambient temperature, for a given pH of the aqueous phase. The oxodiperoxo complexes can be used to carry out epoxidation stoichiometrically and regioselectively with (R)-(+)-limonene, but can also be employed in a catalytic process in a two-phase mixture
HNa2[AsW12O40] 的 Keggin dodecatungstoarsenato 阴离子在
过氧化氢水溶液中固有地不稳定,主要降解为 [AsO4W2O2(-O2)2(O2)2}2]3-、[HAsO4W2O2(-O2)2( O2)2}]2-和[WO(O2)2(
H2O)}2(-O)]2-。这些阴离子以盐的形式被分离出来,并通过元素和光谱分析进行鉴定。式 [(nC6H13)4]3[AsO4W2O2(-O2)2(O2)2}2] 的盐是由
