  铜介导的杂芳基溴与 (phen)CuRF 的全氟烷基化

  摘要：

  在过去的几十年里，将全氟烷基连接到有机化合物上一直是一个主要的合成目标。以前，我们的小组报道了菲咯啉连接的全氟烷基铜试剂 (phen)CuR F，它与芳基碘化物和芳基硼​​酸酯反应形成相应的三氟化苯。本文报道了一系列杂芳基溴化物与 (phen)CuCF 3和 (phen)CuCF 2 CF 3的全氟烷基化。温和的反应条件允许该过程耐受许多常见的官能团。使用 (phen)CuCF 2 CF 3 进行全氟乙基化的产率比使用 (phen)CuCF 3 进行三氟甲基化的产率略高，创建了一种生成氟代烷基杂芳烃的方法，这些杂芳烃不易从三氟乙酸衍生物中获得。
