Polymer ligands that can regulate reaction temperature in “smart” catalysts

“Smart” homogeneous water-soluble catalysts whose activity is inversely dependent on the temperature is presented. The behavior of the catalysts is based on the inverse temperature dependence o the solubility of some polymers which results in high activity at low temperatures and lower activity at elevated temperatures wher the catalyst is phase separated from the continuous phase containing the substrate. The synthesis and applications of the catalysts are presented.
