namely, diazotization of aminoarenes followed by in situ fluoro-dediazoniation of the corresponding diazonium ions, was successfully accomplished to produce fluoroarenes in high yields by using hydrogen fluoride combined with base solutions. The diazotization stage has been found to play the most important part in yielding fluoroarenes effectively. It was greatly influenced by the composition of the HF
通过将
氟化氢与碱溶液结合使用,成功地实现了包括杂芳族化合物在内的
氨基
芳烃的一锅式脱
氨氟化,即
氨基
芳烃的重氮化,然后将相应的重氮离子进行原位
氟脱氮,以高产率生产了
氟芳烃。已发现重氮化阶段在有效生产
氟代
芳烃中起着最重要的作用。它受到HF溶液组成的极大影响,并通过在谨慎控制的条件下使用适量的碱(例如
吡啶)来增强。光
化学方法有效地促进了
氟脱重氮化阶段,从而以高收率提供了具有极性取代基(如羟基,硝基等)的
氟代
芳烃。
