An efficient perfluoroalkylation of unactivated alkenes with perfluoro acid anhydrides was developed. Copper salts play a crucial role as a catalyst to achieve allylic perfluoroalkylation with the in situ generated bis(perfluoroacyl) peroxides. Furthermore, carboperfluoroalkylation of alkene bearing an aromatic ring at an appropriate position on the carbon side chain was found to proceed under metal‐free
已开发了用全氟酸酐对未活化烯烃进行有效的全氟烷基化反应。铜盐在用原位生成的双(全氟酰基)过氧化物实现烯丙基全氟烷基化方面起着至关重要的作用。此外,发现在无金属条件下,在碳侧链上适当位置带有芳香环的烯烃的碳氟烷基化反应可进行,以提供带有全氟烷基的碳环或杂环。该方法利用了容易获得的全氟烷基来源,为将全氟烷基引入sp 3碳上以构建合成有用的骨架提供了方便而强大的工具。
