The synthesis of NH-sulfoximines from sulfides has been first developed under mild conditions in an aqueous solution with surfactant TPGS-750-M as the catalyst at room temperature. In this newly developed process, a simple and convenient recycling strategy to regenerate the indispensable hypervalent iodine(III) is used. The resulting 1,2,3-trifluoro-5-iodobezene can be recovered almost quantitively from the mixture by liquid-liquid extraction and then oxidized to give the corresponding iodine(III) species. This optimized procedure is compatible with a broad range of functional groups and can be easily performed on a gram scale, providing a green protocol for the synthesis of sulfoximines.

在胶束水溶液中使用可回收的高价碘（III）试剂合成NH-亚砜肟类。

在室温下，先在温和的条件下，以表面活性剂TPGS-750-M为催化剂，在温和的条件下从硫化物合成NH-亚砜肟。在这个新开发的过程中，使用了一种简单方便的回收策略来再生必不可少的高价碘（III）。可以通过液-液萃取从混合物中几乎定量地回收得到的1,2,3-三氟-5-碘代苯，然后氧化得到相应的碘（III）。此优化程序可与各种官能团兼容，并且可以轻松地以克为单位进行操作，从而为合成亚砜肟类提供了绿色协议。
