Abstract

The present invention relates to a process for the preparation of perfluoroalkylphosphines comprising at least the reaction of at least one fluoro(perfluoroalkyl)phosphorane with at least one hydride ion donor, and to the use of tris(perfluoroalkyl)phosphines as perfluoroalkylating reagents.
