A hyervalent iodine reagent prepared from o-iodosylbenzoic acid and trifluoromethanesulfonic acid (TfOH) (1:2) showed a high reactivity toward aromatic substrates, giving aryl(o-carboxyphenyl)iodonium triflates in good to high yields. Treatment of the iodine reagent with 1-trimethylsilylalkynes afforded alkynyliodonium triflates bearing carboxy group in high yields. The alkynyliodonium triflates indicated a high efficiency as a Michael acceptor to nucleophiles and the o-carboxyphenyliodonio group behaved as a good leaving group.
