Pd nanoparticles immobilized onto polymer-inorganic hybrid support: Synthesis, characterization and catalytic activity on Suzuki-Miyaura coupling reactions in water

摘要

Polymer-inorganic hybrid support by the combination of poly(N-isopropylacrylamide) (PNIPAM) and silica gel was synthesized as heterogeneous catalysts supports. Pd (0) catalysts immobilized onto this support were prepared and characterized. The Pd catalyzed Suzuki-Miyaura coupling reaction was performed in water and yielded good results. The catalyst is stable in air and the recyclability of the catalyst makes it eco-friendly to use.
