A reagent prepared from a 1:2 molar ratio of (diacetoxy)iodobenzene [PhI(OAc)2] and trifluoromethanesulfonic acid (TfOH) reacts with aromatic compounds to give diaryliodonium triflates in fairly good yields. The high reactivity and high para selectivity of the reagent [PhI(OAc)2-2TfOH] are described.
