Abstract
The multifunctional plateform of poly(di(pyridin-2-yl)methyl acrylate) (PDPyMA), which can coordinate with different metal ions to form the heterogeneous catalysts for various reactions, was obtained by the free radical polymerization of designed functional monomer of di(pyridin-2-yl)methyl acrylate (DPyMA). The insoluble powders formed from PDPyMA and metal salts like Pd(OAc)2 and Cu(OTf)2 have been used to catalyze different reactions such as oxidation of primary alcohol to aldehyde and ketone, Suzuki-Miyaura reactions, and Friedel-Crafts alkylations. The performance of these heterogeneous catalysts was similar or only slightly lower than the soluble monomeric complexes that formed by DPyMA and corresponding metal salts, indicating that the steric hindrance caused by polymeric plateform was not significant. The catalysts based on PDPyMA were recycled by simple filtration and rinse with no observable weight loss nor activity decline.
