用可循环催化体系[(CH3(CH2)17)2N(CH3)2]3[PW4O32]/H2O2/dioxan/olefin.成功地催化了烯烃的环氧化反应这种新的催化体系不仅能够催化烯烃的均相环氧化反应，而且具有独特的反应可控相转移特性，而且避免了氯化溶剂的使用。反应在双氧水/二恶英的两相混合体系中进行，多种烯烃可以高效地转化为相应的环氧化物。用31P魔角核磁共振和红外光谱对新催化剂和旧催化剂[(CH3(CH2)17)2N(CH3)2]3[PW4O32]进行了表征。
The epoxidation of alkenes was successfully catalyzed by a recyclable catalytic system: [(CH3(CH2)17)2N(CH3)2]3[PW4O32]/H2O2/dioxan/olefin. This new catalytic system is not only capable of catalyzing homogeneous epoxidation of alkenes with a unique reaction-controlled phase-transfer character, but also avoids the use of chlorinated solvents. The reactions were conducted in a biphasic mixture of aqueous H2O2/dioxan, and many kinds of alkenes could be efficiently converted to the corresponding epoxides in high yields. Both new and used [(CH3(CH2)17)2N(CH3)2]3[PW4O32] catalyst was characterized by 31P magic angle spin NMR, and IR.
