An efficient approach for enhancing the catalytic activity of Ni-MOF-74 via a relay catalyst system for the selective oxidation of benzylic C-H bonds under mild conditions.

Although nickel-based materials exhibit similar catalytic activity to palladium in organic synthesis, the selective oxidation of inert C-H bonds in the absence of other co-catalysts remains a largely unsolved challenge. This paper introduces a facile and efficient approach for enhancing the catalytic activity of Ni-MOF-74 with [bmim]Br via a relay catalysis strategy, which is excellent for the selective oxidation of benzylic C-H bonds. Notably, the catalyst recycling and scale up experiments demonstrated the practicability of the protocol.

A general and efficient approach for tuning the crystal morphology of classical MOFs.

This communication introduces a general approach toward the size/morphology-controlled synthesis of classical MOFs with 2-methylimidazole (2-MI) as a competitive ligand and a base to accelerate the nucleation of crystallization. A higher concentration of 2-MI and a suitable polarity and solubility of the solvent will accelerate the nucleation of the crystal, resulting in nanometer size particles. However, larger crystals can be obtained via the further growth of nanoparticles with prolonging the reaction time.
