  • 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.
