Reaction Mechanisms of the Direct Epoxidation of Alkenes in the Liquid Phase

Abstract

Reaction mechanisms for the liquid-phase epoxidation of alkenes are reviewed critically: the classical Prilezhaev reaction, catalytic epoxidation with participation of hydrogen peroxide and of organic hydroperoxides, reactions for the production of alkene oxides in the oxidation of unsaturated hydrocarbons, reaction of a combined oxidation of alkenes with aldehydes. The mechanism and prospects of the catalysed oxidation with oxygen of alkenes to epoxides are discussed in detail. 150 references.
