Visible Light‐ and Heat‐Promoted C−O Coupling Reaction of Phenols and Aryl Halides

Abstract A visible light‐ and heat‐promoted C‐O coupling reaction of phenols and aryl halides has been described. Compared to the traditional C‐O coupling reactions promoted by visible light, this strategy avoids the use of transition metals, photocatalysts and ligands. Moreover, the reaction has good substrate universality, suitable for substituted phenol, naphthol and heterocyclic phenol derivatives.
