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
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。
