Alkenyl sulfones can be stereoselectively synthesized from alkenes or alkynes using sodium sulfinates. The reaction can be performed by a copper-catalyzedoxidation of sodium sulfinates in air. The reaction of alkenes gives (E)-alkenyl sulfones via anti addition of sulfonyl cation and elimination process. Furthermore, the employment of alkynes produces (E)-β-haloalkenyl sulfones in the presence of
