Provided is a method for producing a perfluoroalkylated compound at low cost, safely and with high efficiency. A method for producing a perfluoroalkylated compound, comprising reacting a bis(perfluoroalkanoyl) peroxide with a compound having a carbon-carbon unsaturated bond and/or an aromatic ring having a hydrogen atom bonded thereto in the presence of a copper catalyst.
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

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
