A highly efficient copper‐mediated aromatic pentafluoroethylation method using TMSCF3 as the sole fluoroalkyl source is described. The reaction proceeds by a key C1 to C2 process, that is, the generation of CuCF3 from TMSCF3, followed by a subsequent spontaneous transformation into CuC2F5. Various aryl iodides were pentafluoroethylated with the TMSCF3‐derived CuC2F5. This method represents the first
描述了一种高效的铜介导的芳香族五氟乙基化方法,该方法使用TMSCF 3作为唯一的氟代烷基来源。反应的进行通过密钥C 1至C 2的处理,即,CuCF的产生3从TMSCF 3,之后进行随后的自发转变为CUC 2 ˚F 5。各种芳基碘化物都用TMSCF 3衍生的CuC 2 F 5进行了五氟乙基化。该方法代表了使用市售的TMSCF 3作为五氟乙基前体对芳基碘进行五氟乙基化的第一种实用而有效的方法。
