An iodine-catalyzed functionalization of various olefins and alkynes and direct decarboxylative functionalization of cinnamic and propiolic acids with TosMIC provides highy valuable vinyl, allyl, and β-iodo vinylsulfones. This simple, efficient, and environmentally benign approach is attractive to both synthetic and medicinal chemistry.
