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

Palladium nanoparticles were immobi- lized on PNIPAM:4-VP hydrogels. The resultant palladium catalysts showed high activities for Suzuki-Miyaura coupling reactions in water. The recyclability of the catalysts was improved by using 4-VP as a co-monomer in the hydrogels due to re- duced Pd leaching during the reactions.
