Abstract

A ligand-free catalytic epoxidation system using permanganate in a surfactant-like ionic liquid (IL) medium was developed. The results indicate that the IL takes crucial effects in the epoxide selectivity. The loading of permanganate is also found critical in preventing over-oxidation of epoxides. The system with 0.3 mol% permanganate and 3.5-equivalent CH₃CO₃H is able to achieve excellent yields and selectivity of epoxides. The study of epoxidation with KMnO₄ in IL medium reveals an unusual oxidation behavior of permanganate not found in traditional solvents. Copyright © 2015 Elsevier B.V.
