A novel palladium N-heterocyclic bis-carbene dicarboxylate ligand (Pd-NHDC-H₂L) was successfully synthesized. In addition, an Pd-NHDC-containing UiO-67 type MOF (UiO-67-Pd-NHDC) was prepared on the basis of a size-matched ligand mixture of biphenyl-4,4′-dicarboxylic acid/Pd-NHDC-H₂L (9/1) and ZrCl₄ under solvothermal conditions. The obtained UiO-67-Pd-NHC MOF can be a highly heterogeneous catalyst to promote Heck cross-coupling and intermolecular benzyne-benzyne-alkene insertion reactions.
