Copper‐mediated pentafluoroethylation of arenediazonium tetrafluoroborates with tetrafluoroethylene (TFE) on‐site generated from TMSCF3 has been developed as a new method to prepare pentafluoroethyl arenes. The active pentafluoroethylation reagent “CuC2F5” is pre‐generated from CuSCN, TFE and CsF, and its generation and further reaction are strongly solvent‐dependent. This pentafluoroethylation reaction
已经开发了由TMSCF 3现场产生的四氟硼酸芳族二唑鎓与四氟乙烯(TFE)的铜介导的五氟乙基化,这是制备五氟乙基芳烃的一种新方法。活性五氟乙基化试剂“ CuC 2 F 5 ”是由CuSCN,TFE和CsF预先生成的,其生成和进一步的反应强烈依赖于溶剂。该五氟乙基化反应代表了Sandmeyer型五氟乙基化的第一个例子,它具有良好的官能团耐受性,并且在合成复杂的生物活性化合物方面具有潜在的应用价值。
