Synergistic crystalline catalysts assembled with Wells–Dawson-type polyoxometalates and heterovalent metal complexes for efficient benzylic C–H bond oxidation

Two synergistic crystalline catalysts assembled with Wells–Dawson-type [P 2 W 18 O 62 ] 6− cluster and heterovalent Cu complexes were synthesized for benzylic C–H oxidation, with high DPM conversion and a distinct radical-mediated oxidation mechanism.
