Palladium Nanoparticles on Thermoresponsive Hydrogels and their Application as Recyclable Suzuki-Miyaura Coupling Reaction Catalysts in Water

Palladium nanoparticles were immobilized on PNIPAM:4-VP hydrogels. The resultant pualladium catalysts showed high activities for SuzukiMiyaura coupling reactions in water. The recyclability of the catalysts was improved by using 4-VP as a co-monomer in the hydrogels due to reduced Pd leaching during the reactions.This research is partially supported by the Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology (2011-00000001765).
