Cu-mediated protocol toward the 1,2-bis-perfluoroalkyaltion of alkenes/alkynes was developed. The method proceeded with perfluorocarboxylic anhydrides as inexpensive and readily available perfluoroalkyl sources. Diacyl peroxide was generated in situ from the perfluorocarboxylic anhydrides and H2O2. The key step in this reaction is the formation of a stable perfluoroalkylcopper intermediate that is achieved
开发了一种新型的、Cu 介导的烯烃/炔烃 1,2-双全氟烷基化方案。该方法使用全氟羧酸酐作为廉价且容易获得的全氟烷基源进行。由全氟羧酸酐和H 2 O 2原位生成过氧化二酰基。该反应的关键步骤是在联吡啶配体的帮助下形成稳定的全氟烷基铜中间体。中间体与含全氟烷基的烷基或乙烯基的后续反应得到所需产物。
