A new method for the formation of 1,1‐difluoroethyl copper species (“CuCF2CH3”) with 1,1‐difluoroethylsilane (TMSCF2CH3) has been developed. The “CuCF2CH3” species can be applied to the efficient 1,1‐difluoroethylation of diaryliodonium salts under mild conditions, affording (1,1‐difluoroethyl)arenes in good to excellent yields. This convenient procedure tolerates a wide range of functional groups
开发了一种新的与1,1-二氟乙基硅烷(TMSCF 2 CH 3)形成1,1-二氟乙基铜物质(“ CuCF 2 CH 3 ”)的方法。“ CuCF 2 CH 3 ”物质可以在温和的条件下有效地用于二芳基碘鎓盐的有效1,1-二氟乙基化反应,从而以良好的产率提供优异的(1,1-二氟乙基)芳烃。这种方便的方法可耐受各种官能团,因此可作为将CF 2 CH 3基团引入复杂分子的实用合成工具。
