Diaryliodine(III) salts are versatile reagents and well investigated compounds in organic synthesis. Most of diaryliodine(III) compounds can be prepared from hypervalent iodine(III) reagents with arenes under oxidative reaction conditions. Recently, our group reported the synthesis and structural investigation of a new active hypervalent iodine(III) species, 2-[hydroxy(trifluoromethanesufonyloxy)]-iodobenzoic acid (IBA–TfOH), which was prepared by the treatment of 2-iodosylbenzoic acid with trifluoromethanesulfonic acid, and the prepared reagent could be used as an oxidant for many substrates. Herein, we report a synthesis and structural investigation of pseudocyclic diaryliodine(III) salts, which can be prepared from IBA-TfOH and arenes in the presence of trifluoromethanesulfonic acid. Prepared pseudocyclic diarliodine(III) salts can be converted to the cyclic diarliodine(III) compounds.
