Abstract

The invention relates to a method for producing perfluoroalkyl phosphines, comprising at least one step in which at least one fluoro(perfluoroalkyl)phosphorane is reacted with at least one hydride ion donator, and the use of tris(perfluoroalkyl)phos-phines as perfluoroalkylating reactants.
