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.
