A reagent [PhIO-TfOH] prepared by mixing iodosylbenzene and triflic acid undergoes electropholic addition to various alkynes under mild conditions. The addition is a highly stereoselective anti-addition and provides (E)-[β-(trifluoromethanesulfonyloxy)vinyl]iodonium triflates in good to high yields.
