CA 2487475

The invention relates to a method of creating a carbon-carbon or carbon-heteroatom linkage by reacting an unsaturated compound bearing a leaving group and a nucleophilic compound. More specifically, the invention relates to the creation of a carbon-nitrogen linkage involving the arylation of nitrogenous organic derivatives. The inventive method consists in creating a carbon-carbon or carbon-heteroatom linkage by reacting an unsaturated compound bearing a leaving group and a nucleophilic compound providing a carbon atom or a heteroatom (HE) capable of being substituted for the leaving group, thereby creating a C-C or C-HE linkage. The invention is characterised in that the reaction is carried out in the presence of an effective quantity of a catalyst based on copper and at least one ligand comprising at least one imine function and at least one additional nitrogen atom as chelating atoms.

La présente invention a pour objet un procédé de création d'une liaison carbone-carbone ou carbone-hétéroatome par réaction d'un composé insaturé porteur d'un groupe partant et d'un composé nucléophile. L'invention vise notamment la création de liaison carbone-azote selon un procédé d'arylation de dérivés organiques azotés. Le procédé, selon l'invention, de création d'une liaison carbone-carbone ou carbone-hétéroatome par réaction d'un composé insaturé porteur d'un groupe partant et d'un composé nucléophile apportant un atome de carbone ou un hétéroatome (HE) susceptible de se substituer au groupe partant, créant ainsi une liaison C-C ou C-HE, est caractérisé par le fait que la réaction a lieu en présence d'une quantité efficace d'un catalyseur à base de cuivre et d'au moins un ligand comprenant au moins une fonction imine et au moins un atome d'azote supplémentaire comme atomes de chélation.
