Organofluorine compounds are widely used in all aspects of the chemical industry. Although tetrafluoroethylene (TFE) is an example of an economical bulk organofluorine feedstock, the use of TFE is mostly limited to the production of poly(tetrafluoroethylene) and copolymers with other alkenes. Furthermore, no catalytic transformation of TFE that involves carbon-fluorine bond activation has been reported
有机氟化合物广泛应用于化学工业的各个方面。尽管四氟乙烯 (TFE) 是经济的散装有机氟原料的一个例子,但 TFE 的使用主要限于生产聚(四氟乙烯)和与其他烯烃的共聚物。此外,迄今为止还没有报道涉及碳-氟键活化的 TFE 催化转化。我们在此报告了在碘化锂存在下,钯催化的 TFE 与芳基锌试剂偶联反应的第一个例子,以优异的产率得到 α,β,β-三氟苯乙烯衍生物。
