Palladium-catalyzed ortho-functionalization of azoarenes with aryl acylperoxides

With the aid of an azo directing group, Pd-catalyzed ortho-sp(2) C-H bond activation/functionalization of azoarenes with aryl acyl peroxides has been explored. This transformation provides easy access to regioselectively introducing acyloxyl and aryl groups into azoarenes by simply changing the reaction temperature and solvent.
