Selectfluor in fluorodecarboxylations of both mono- and difluoroaryloxy acetic acid derivatives. This method efficiently converts a wide range of neutral and electron-poor substrates to afford the desired di- and trifluoromethyl aryl ethers in good to excellent yields. The purifications are facile, and the reaction times are less than 5 min, which makes these fluorodecarboxylations promising for future PET-imaging
在单和二氟芳氧基乙酸衍生物的氟脱羧反应中,XeF 2被证明是比NFSI或Selectfluor更有效的氟转移试剂。该方法有效地转化了多种中性和电子贫乏的底物,以良好至极好的收率提供了所需的二氟和三氟甲基芳基醚。纯化很容易,反应时间少于5分钟,这使得这些氟代脱羧有希望用于未来的PET成像应用。
