Accessing Sterically Congested Benzannulated Cyclic Aryl Ethers via Photoredox Decarboxylative Giese-Type C2–C3 Bond Formation

The visible-light-driven photocatalytic decarboxylation of α-aryloxy carboxylic acids produces α-oxy carbon-centered radicals that undergo intramolecular Giese addition to form 2,3-dihydrobenzofurans, chromans, 2,3,4,5-tetrahydrobenzo[b]oxepines, and 3,4,5,6-tetrahydro-2H-benzo[b]oxocines. In contrast to the existing m...
