  • Iron-copper co-catalyzed process for carbon-carbon or carbon-heteroatom bonding
    Patent number: 9162953
    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.

  • Method for the preparation of phosphine butadiene ligands, complexes thereof with copper and use thereof in catalysis
    Patent number: 8674125
    Abstract: A method for the creation of a carbon-carbon (C—C) bond or of a carbon-heteroatom (C-HE) bond includes reacting a compound carrying a leaving group with a nucleophilic compound carrying a carbon atom or a heteroatom (HE) capable of replacing the leaving group, thus creating a C—C or C-HE bond, in which process the reaction is carried out in the presence of an effective amount of a catalytic system comprising at least one copper/butadienylphosphine complex.

  • Method for forming a carbon-carbon or carbon-heteroatom bond
    Publication number: 20090240061
    Abstract: The invention relates to a method for forming a carbon-carbon or carbon-heteroatom bond by reacting an unsaturated compound carrying a leaving group and a nucleophilic compound, in the absence of a ligand. The aim of the invention is especially to form carbon-nitrogen bonds according to a method for the arylation of nitrogenated organic derivatives. According to the inventive method, a carbon-carbon or carbon-heteroatom bond is formed by reacting an unsaturated compound carrying a leaving group with a nucleophilic compound donating a carbon atom or a heteroatom (HE) that can substitute the leaving group, thus forming a C—C or C—HE bond, in the presence of a copper-based catalyst and a base. Said metal is characterised in that the reaction takes place in the absence of a ligand and in a nitrile-type solvent.
