Advances and Trends in Polymer Supported Catalyst

Abstract

In this article the author explains recent advances and trends in the researches of polymer supported catalysts. First, he discussed the problems in commercialization of the polymer supported catalyst, namely ; separation & stabilization of the catalyst, acceleration of diffusion of reactants in the catalyst. Second, new polymer supports and reaction systems are introduced, which have been developed in order to accelerate the reaction. Third, polymer supported catalysts in a broad sense are classified into seven categories, and four of them are discussed about their specificities. Finally, sequential multistep reaction, asymmetric reaction, and macrocyclization are described as examples of the cases where the results of the reaction are controlled by the “polymer effect” of the ligand.
