  has not been applied in organic synthesis except the formation of disulfones by self-dimerization of sulfonyl radicals. In this article, they were introduced as new sulfonylating reagents and their combinations with NIS and Et3N were established as excellent iodosulfonylating reagents for alkenes. Finally, a highly efficient method for the synthesis of (E)-vinyl sulfones was developed by mixing an alkene

  N，N'-二磺酰基肼早在半个世纪以前就已被证明是所有类型的磺酰基取代的肼中最具反应性的磺酰基自由基的前体。但是除了通过磺酰基自由基的自二聚形成二砜以外，这种功能还没有用于有机合成。在本文中，将它们作为新的磺酰化试剂进行介绍，并将它们与NIS和Et 3 N的组合确立为烯烃的优异碘磺酰化试剂。最后，通过在室温下将烯烃，N，N'-二磺酰肼，NIS和Et 3 N在THF中混合5分钟，开发了一种高效的（E）-乙烯基砜合成方法。

  A method for the synthesis of (E)-vinyl sulfones and alkynyl sulfones through the cleavage of thiosulfonate promoted by the formation of EDA complexes under visible light irradiation at room temperature without the need for other metal catalysts is described. The mechanism study shows that sodium iodide and thiosulfonate form EDA complexes under visible light irradiation, resulting in a single-electron

  An improved one-pot method to synthesize vinyl sulfones from unsaturated systems by using molecular iodine/sodium arenesulfinate/sodium acetate as reagents was described. Vinyl sulfones derived from styrene derivatives were generally obtained in good to excellent yields except for those bearing strong electron releasing substituent. Aliphatic alkenes and activated alkenes gave the corresponding vinyl sulfone products in moderate to good yields. Arylacetylenes yielded the respective -iodovinyl sulfones in good yields while low yield was observed with aliphatic terminal alkyne. The potentials of the method entail simplicity, short reaction time, non-anhydrous reaction conditions, employing inexpensive, non-metallic reagent and integrating two reactions that are commonly accomplished separately into a single operation.
