  Preparation of (p-phenylene)bis(aryliodonium) ditriflates and their double substitution by some nucleophiles

  摘要：

  A reagent prepared from a 1:1 molar mixture of PhIO and Tf2O or from a 1:2 molar mixture of PHIO and TfOH shows high reactivity toward aromatic substrates and gives (p-phenylene)bis(aryliodonium) ditriflates (8). Interaction of the reagent [PhIO-Tf2O] with cyclohexene suggests that it has a p-[phenyl[(trifluoromethanesulfonyl)-oxy]iodo]phenyliodine(III) structure. Reactions of (p-phenylene)bis(aryliodonium) ditriflates with pyridine, triphenylphosphine, or diphenyl sulfide give doubly para-substituted benzene derivatives in good to high yields.
