Summary: In this study, a polymer network containing N-heterocyclic carbene palladium (PNNHC-Pd) catalytic active sites was fabricated through an immobilization process. The N-heterocyclic carbene palladium dispersed homogeneously in the polymer network, leading to excellent catalytic activity, high stability, and superior reusability in the palladium-catalyzed Suzuki-Miyaura coupling reaction in aqueous medium. This work provides a new insight into the heterogenization of homogeneous catalysts based on polymer network.

Summary: The catalytic activities of palladium nanoparticles on a polyaniline support were improved by tungsten doping, resulting in a significantly increased catalyst turnover number (>10(4)) for the Suzuki-Miyaura coupling reaction. Characterization of the materials showed that tungsten doping improved the micro-morphology, leading to more efficient absorption of reactants. Additionally, tungsten facilitated stabilization of Pd(0) species and the transmetallation step, both crucial for the catalytic reaction. Therefore, Pd/W@PANI engineering material may serve as a highly efficient heterogeneous catalyst in the pharmaceutical industry.
