Trifluorovinylzinc is a common synthetic intermediate for trifluorovinyl derivatives, including α,β,β-trifluorostyrenes and hexafluorobutadiene. Here, we report a novel synthetic approach for the formation of trifluorovinylzinc chloride via a C–F bond activation of tetrafluoroethylene (TFE), which is an industrially cost-effective bulk feedstock with a negligible GWP. The present system provides a
三氟乙烯基锌是三氟乙烯基衍生物(包括α,β,β-三氟苯乙烯和六氟丁二烯)的常见合成中间体。在这里,我们报告了一种通过四氟乙烯(TFE)的CF键活化形成三氟氯乙烯锌的新颖合成方法,这是一种工业上具有成本效益的散装原料,其全球升温潜能值可忽略不计。本系统提供了以非常低的能量消耗制备各种三氟乙烯基衍生物的实用合成路线。
