A new process involving copper-catalyzed aerobic C(sp(2))-H activation, followed by cycloetherification, has been developed. This reaction serves as a direct method for the preparation of multisubstituted dibenzofurans starting with o-arylphenols. The presence of a strong para-electron-withdrawing group (e.g., NO(2)) on the phenol is essential for the success of the reaction.
