A general approach to fluorinated (hetero)aromatic derivatives is elaborated. The key reaction is a deoxofluorination of substituted acetophenones with sulfur tetrafluoride (SF4). In contrast to previous deoxofluorination methods, this transformation is fast, scalable (up to 70 g), and high-yielding. More than 100 novel or previously hardly accessible fluorinated heterocycles, interesting for medicinal
详细阐述了氟化(杂)芳族衍生物的一般方法。关键反应是取代苯乙酮与四氟化硫 (SF 4 )的脱氧氟化。与之前的脱氧氟化方法相比,这种转化速度快、可扩展(高达 70 g)且产量高。合成了 100 多种新颖的或以前难以获得的氟化杂环,对药物化学和农业化学很感兴趣。
