Herein, we present a novel strategy for synthesizing polyfluorinated compounds by the fluorotrifluoromethylation of olefins, which was achieved through a new trifluoromethyl-iodine(III) reagent TFNI-1. TFNI-1 was readily synthesized via a three-step process, and its structure was characterized by NMR spectroscopy and X-ray crystallography. It is shown by radical trapping and radical clock experiments that the reaction involves the CF₃ radical intermediate.

高价三氟甲基碘 (III) 试剂介导的烯烃的氟三氟甲基化

在此，我们提出了一种通过烯烃的氟三氟甲基化合成多氟化合物的新策略，这是通过新型三氟甲基碘(III)试剂TFNI-1实现的。TFNI-1很容易通过三步法合成，并通过 NMR 光谱和 X 射线晶体学对其结构进行了表征。自由基捕获和自由基时钟实验表明该反应涉及CF ₃自由基中间体。
