CuI/2-(2,6-dimethylphenylamino)-2-oxoacetic acid (DMPAO) as an efficient catalytic combination was used for the hydroxylation of aryl bromides. The catalyst loading is low to 2 mol% and substituted phenols could be prepared in wide assembly. In addition, by modifying the mixed solvent and base the symmetrical diaryl ethers could be synthesized conveniently from aryl bromides.

Key words: copper, Ullmann reaction, 2-(2,6-dimethylphenylamino)-2-oxoacetic acid, hydroxylation, phenol
