A new method for the on-site preparation of tetrafluoroethylene (TFE) and a procedure for its efficient use in pentafluoroethylation by fluoride addition were developed by using a simple two-chamber system. The on-site preparation of TFE was accomplished by dimerization of difluorocarbene derived from (trifluoromethyl)trimethylsilane (TMSCF₃) under mild conditions. Other fluoroalkylation reactions, such as (aryloxy)tetrafluoroethylation and tetrafluoroethylation processes, were also achieved using a similar approach. This work not only demonstrates a convenient and safe approach for the generation and use of TFE in academic laboratories, but also provides a new strategy for pentafluoroethylation.

TMSCF3作为五氟乙基化，（芳氧基）四氟乙基化和四氟乙基化的CF2 = CF2的便捷来源

通过使用简单的两腔系统，开发了一种现场制备四氟乙烯（TFE）的新方法及其通过添加氟化物有效地用于五氟乙基化的方法。TFE的现场制备是通过在温和条件下将衍生自（三氟甲基）三甲基硅烷（TMSCF ₃）的二氟卡宾进行二聚完成的。其他的氟烷基化反应，例如（芳氧基）四氟乙基化和四氟乙基化过程，也可以使用类似的方法来实现。这项工作不仅证明了在实验室中生成和使用TFE的便捷安全方法，而且为五氟乙基化提供了新的策略。
