Supported catalysts from polymerizable transition metal complexes

This review covers the last 12 years of research on the synthesis and use of heterogeneous catalysts obtained by co-polymerization of suitable metal containing monomers (MCM). The catalytic applications of these supported metal complexes are subdivided into three areas. Hydrogenation of alkenes and functionalized olefins are covered first. Oxidation of several substrates such as olefins, sulfides, alcohols, and aldehydes are then considered. Of particular interest in this framework is the use of chiral salen metal containing monomers for the stereoselective epoxidation of hindered olefins. Alkene and alkyne polymerizations, Heck and Heck-type reactions, allylic alkylation, and Michael additions are discussed in the field of carbon-carbon bond forming reactions. A common factor emerging from this survey is the application of metal containing monomers for the synthesis of molecularly imprinted polymers to be used as catalysts or catalyst supports.
