A series of pentafluoroethylation reactions of styrene derivatives are described using the [CuCF₂CF₃] reagent prepared from low-cost pentafluoroethane (HCF₂CF₃). Under aerobic conditions, chloropentafluoroethylation, dimerization-pentafluoroethylation, vinylic pentafluoroethylation, formyloxylation-pentafluoroethylation and hydroxypentafluoroethylation can be achieved using styrenes to generate various functionalized products containing the CF₂CF₃ group. It is remarkable that a single reagent is capable of such divergent reactivities with readily available feedstocks.

使用 CuCF2CF3 对苯乙烯衍生物进行发散性五氟乙基化


使用由低成本五氟乙烷 (HCF ₂ CF ₃ CF ₃ ] 试剂描述苯乙烯衍生物的一系列五氟乙基化反应）。在有氧条件下，苯乙烯可进行氯五氟乙基化、二聚-五氟乙基化、乙烯基五氟乙基化、甲酰氧基化-五氟乙基化和羟基五氟乙基化，生成各种含有CF ₂ CF ₃ 基团的官能化产物。值得注意的是，单一试剂能够与容易获得的原料发生如此不同的反应。
