fluorine: The direct synthesis of CuCF3 from a cuprate reagent and trifluoromethyl ketones, as one of the most economical and efficient trifluoromethyl sources, was accomplished. The advantages of this method are all of reagents employed are low‐cost, operation is simple, and the yield of CuCF3 is virtually quantitative (see scheme). Furthermore, three types of trifluoromethylations smoothly proceeded
用氟经济:由铜酸盐试剂和三氟甲基酮(最经济,最有效的三氟甲基来源之一)直接合成CuCF 3。该方法的优势在于所使用的所有试剂成本低,操作简单且CuCF 3的产率实际上是定量的(请参阅方案)。此外,三种类型的三氟甲基化顺利进行以提供高产率的相应产物。
