The cerium(IV) ammonium nitrate (CAN) mediated reaction of aryl sulfinates and sodium iodide with alkenes afforded vinyl sulfones in very good yields. Alkynes underwent a similar reaction to give β-iodovinyl sulfones, which on treatment with potassium carbonate afforded the corresponding acetylenic sulfones in high yields.
