Abstract: The invention relates to a fluorocarbon polymer material comprising a backbone with the following unit: wherein: Z is a quaternary ammonium group, Y1 and Y2 are each independently an oxygen heteroatom or a sulphur heteroatom, A is a fluorinated or perfluorinated straight chain having from 2 to 6 carbon atoms, R1 represents a phenyl or aryl group or a —CR2R3— group, and R4 is selected from the group consisting of a hydrogen atom, a straight or branched, cyclic or acyclic, alkyl or halogenated alkyl group, and a group represented by the following formula: m is an integer comprised between 0 and 10, preferably between 0 and 3; m?, n and r are integers, each independently equal to 0 or 1; and s is equal to 0 or 1, provided that when s is equal to 0, then R4 is different from the hydrogen atom.

Abstract: The present invention relates to a process for creating a Carbon-Carbon bond (C—C) or a Carbon-Heteroatom bond (C—HE) by reacting a compound carrying a leaving group with a nucleophilic compound carrying a carbon atom or a heteroatom (HE) that can substitute for the leaving group, creating a C—C or C—HE bond, wherein the reaction takes place in the presence of an effective quantity of a catalytic system comprising iron and copper.
