Alkenyl sulfones can be stereoselectively synthesized from alkenes or alkynes using sodium sulfinates in the presence of CuI-bpy as catalyst and oxygen. The reaction of alkenes gives (E)-alkenyl sulfones via anti addition of the sulfonyl cation followed by an elimination process. Furthermore, the employment of alkynes produces (E)-β-haloalkenyl sulfones in the presence of potassium halides.
