The bisaziridination reaction of symmetric (E-s-trans-E)-α-diimines using ethyl nosyloxycarbamate as aminating agent yields symmetrically functionalized bidiaziridines, under mild conditions. The reactions take place with very high stereoselectivity givin

Page/Page column 21-22, (2010/02/14)
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

Page 18-19, (2008/06/13)
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.
