Abstract: The present invention concerns a process for arylating or vinylating or alkynating a nucleophilic compound. More particularly, the invention concerns arylating nitrogen-containing organic derivatives. The arylating or vinylating or alkynating process of the invention consists of reacting a nucleophilic compound with a compound carrying a leaving group and is characterized in that the reaction is carried out in the presence of an effective quantity of a catalyst based on a metallic element M selected from groups (VIII), (Ib) and (IIb) of the periodic table and at least one ligand comprising at least one imine function and at least one supplemental nitrogen atom as the chelating atoms.

Abstract: The present invention concerns a process for arylating or vinylating or alkynating a nucleophilic compound. More particularly, the invention concerns arylating nitrogent-containing organic derivatives. The arylating or vinylating or alkynating process of the invention consists of reacting a nucleophilic compound with a compound carrying a leaving group and is characterized in that the reaction is carried out in the presence of an effective quantity of a catalyst based on a metallic element M selected from groups (VIII), (Ib) and (IIb) of the periodic table and at least one at least bidentate ligand comprising at least two chelating atoms, namely at least one oxygen atom and at least one nitrogen atom.

Abstract: 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.

Abstract: The present invention concerns a process for creating a carbon-carbon or carbon-heteroatom bond by reacting an unsaturated compound carrying a leaving group with a nucleophilic compound. The invention also concerns the creation of a carbon-nitrogen bond using a process for arylating organic nitrogen-containing derivatives. The process of the invention is a process for creating a carbon-carbon or carbon-heteroatom bond by reacting an unsaturated 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, characterized in that the reaction takes place in the presence of an effective quantity of a catalyst based on a metallic element M selected from group (VIII), (IB) and (IIB) of the periodic table and at least one at least bidentate ligand comprising at least two chelation atoms, namely at least one oxygen atom and at least one nitrogen atom.

Abstract: The invention concerns novel catalysts for aromatic nucleophilic substitution. Said catalysts are compounds of the general formula (I), wherein: R1, R2, R3, R4, R5, and R6, identical or different, are selected among hydrocarbon radicals; the Pn's, advantageously the same, are selected among metalloid elements of column V of a period higher than nitrogen; Z is a metalloid element of column V, advantageously distinct from Pn; preferably a nitrogen (N, P, As, Sb). The invention is applicable to organic synthesis.
