Abstract

β-Iodovinyl sulfones were synthesized in high yields (89–99%) via a regioselective radical double functionalization of terminal arylalkynes with tosyl iodide, using equivalent reagent amounts. This efficient reaction was performed under irradiation with red light of 625 nm from an economical LED light source.
