Photoredox reactions of quinones are reviewed, that enable C-H bond oxidation at the vicinity of the excited quinone carbonyl and concomitant reduction of the quinone under photoirradiation. Mechanistic insights on the benzo-, naphtho-, and anthraquinones are discussed. Also the potential utilities in organic synthesis are described.
Keywords: C−H functionalization; natural products; photochemistry; quinones; redox reaction.
