Abstract

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.
