An efficient and highly regioselective synthesis of 2-alkoxy aromatic azo compounds via palladium­(II)-catalyzed alkoxylation of azobenzene derivatives directed by the azo group using alcohols as the alkoxylation reagents and PhI­(OAc)2 as the oxidant has been developed. The method is applicable to both primary and secondary alcohols and affords moderate to good yields.
