A novel molecular scaffold with distinct features (easily attachable, removable, recoverable) induces Pd-catalyzed oxidative olefinations when attached to arene alcohols.
The reactions of 2-methoxyethoxymethyl (MEM) ethers 1 with a catalytic amount of cerium(IV) ammonium nitrate (CAN) in acetic anhydride gave the corresponding mixed acetal esters 2 and acetates 3.

Direct C-H functionalization and arylation of benzyl ethers has been accomplished via photoredox organocatalysis. The productive merger of a thiol catalyst and a commercially available iridium photoredox catalyst in the presence of household light directly affords benzylic arylation products in good to excellent yield. The utility of this methodology is further demonstrated in direct arylation of 2,5-dihydrofuran to form a single regioisomer.
