Coordination-Assembly of a Redox-Active Pd6L3 Cage for Aerobic C(sp3)–H Bond Photooxidation of Aromatic Cyclic Ethers

A redox-active Pd6L3 cage with a large lantern-shaped cavity has been synthesized and characterised by NMR, ESI-TOF-MS and X-ray diffraction analysis, which shows exceptional catalytic activity in the selective aerobic C-H photooxidation of aromatic cyclic ethers under mild conditions.
