Abstract: Reaction-controlled phase-transfer catalysis is a new catalytic system. This catalytic system is homogeneous during the reaction. After the reaction the catalyst becomes insoluble solid and precipitates from the reaction medium, so that the catalyst can be easily separated and reused. This paper presents recent progress made in reaction-controlled phase transfer catalysis for the epoxidation of olefins, oxidation of alcohols, hydroxylation, reductive carbonylation of nitroaromatics, esterification, and other reactions by us and other groups.

Key words: reaction-controlled phase-transfer catalysis, oxidation, hydrogen peroxide, carbonylation, esterification
