Ultrafine Palladium Embedded in N-doped Porous Carbon Material from Carbazole-covalent Triazine Polymer for Green Suzuki-Miyaura Coupling Reaction

Here, we develop a facile synthesis route to fabricate ultrafine palladium nanoparticles embedded in N-doped porous carbon material (Pd@N-PCM), in which carbazole-covalent triazine polymers obtained by Friedel-Crafts alkylation at room temperature are used as precursor of N-doped carbon. The obtained Pd@N-PCM as a green catalyst shows the high catalytic efficiency (TOF=982 h⁻¹) for Suzuki-Miyaura coupling reaction of chlorobenzene under the mild reaction condition (room temperature, a non-toxic solvent and air atmosphere). The brilliant catalytic activity of Pd@N-PCM gives the credit to the concerted effect from the ultrafine Pd and N-doped porous carbon.
