ABSTRACT The reaction-controlled phase-transfer catalysis is a new catalytic system. The 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 will present recent progress made in reaction-controlled phase-transfer catalysis for the epoxidation of olefins, oxidation of alcohols, cleavage of the double bond of olefins, oxidation of benzene to form phenol, reduction and reductive carbonylation of nitroaromatics in detail. The stability of the catalyst in recycle and the proposed mechanism of this catalytic system will be summarized and discussed.
