An efficient and highly chemoselective iodination of alkynes using a sulfoniumiodate(I) electrophilc reagent under metal-free conditions has been realized. The reactivity of sulfoniumiodate(I) salt could be significantly diverse in the presence of water as the solvent, enabling the (E)-1,2-diiodoalkenes stereospecifically. This stereodivergent approach is amenable to a wide range of alkyne substrates

A new approach to the stereospecific diiodination of alkynes under mild conditions has been developed. This protocol employs ammonium persulfate as an oxidant and iodide as an iodine source, and provides a highly efficient and general method for the preparation of a broad range of (E)-diiodoalkenes in water.
