A (p-phenylene)bisiodine(III) reagent prepared from iodosylbenzene and trifluoromethanesulfonic acid or the anhydride showed a high reactivity to alkynes. The reaction of alkynes proceeded with stereoselective addition to the carbon–carbon triple bond to give trans-alkenyl(p-phenylene)bisiodonium ditriflates, whereas the reaction of 1-trimethylsilyl-1-alkynes afforded alkynyl(p-phenylene)bisiodonium ditriflates. These reactions indicate that the (p-phenylene)bisiodine(III) reagent is accessible for a (p-phenylene)bisiodine(III) transfer agent.
