afford meta‐substituted biaryls in moderate to good yields. The reaction proceeds via carboxyl‐directed intermolecular cross‐dehydrogenative coupling and subsequent decarboxylation. The new C−C bonds in this transformation are formed in the ortho position of carboxyl and the reaction tolerates electron‐rich acids. Both symmetrical and unsymmetrical meta‐substituted biaryls can be directly synthesized
