Abstract

Through Pd catalyzed C-N coupling reaction, Pd nanoparticles and diadamantylphosphine ligand were immobilized in situ into the formed N contained polymers as heterogeneous Pd catalysts for Suzuki-Miyaura reaction. The Pd@NPad₂-1.0 catalyst was found to be highly efficient and only 4 ppm of Pd (Pd@NPad₂-1.0) was required for the coupling of aryl bromides with phenylboronic acid, and the corresponding products were obtained in good to excellent yields with high TON and TOF as 250,000 and 41,666 h^{- 1} respectively. Moreover, the coupling of various aryl chlorides with phenylboronic acids gave the corresponding products in high yields also. And the Pd@NPad₂-1.0 catalyst is reusable at least 5 times with only slight deactivation.
