Abstract

Abstract: In the presence of H2O2, the epoxidation of α, β-unsaturated ketones cata lyzed by quaternary ammonium heteropolyphosphato-tungstate was studied. The facto rs such as different solvents, reaction temperature, catalyst amount, reaction time, and substrate concentration were investigated. Epoxidation of α , β-unsaturated ketones can be easily performed in this catalytic system. Under the optimized reaction conditions an epoxy-4-meth yl-3-penten-2-one yield of 87% was obtained.

Key words: α, β-unsaturated ketone, epoxidation, quaternary ammonium heteropolyphosphatotungstate
