Activation de liaisons carbone-halogène et carbone-azote par des catalyseurs de nickel(0) ligandés par un carbène N-hétérocyclique

Abstract : This work describes the preparation of new nickel catalysts liganded with N-heterocyclic carbenes for the reduction of (poly)halogenated arenes and imines and for the N,N'-diarylation of aromatic diamines. In a first part, the Ni(0)/IMes (1/2) catalyst, associated to i-PrONa, was used for the reduction of (poly)chlorinated arenes. Carbon-fluorine bonds of fluoroarenes can also be activated by the Ni(0)/IMes (1/1) catalyst and be reduced in the presence of the secondary alkoxide Et2CHONa. Transfer hydrogenation of imines into amines is also possible with this catalyst. In the second part, the development of a new nickel catalyst, noted Ni(0)/IPr (1/2), for the N,N'-diarylation of aromatic diamines is described. The synthesis of new N,N'-diaryldiamines containing a 4-[10-(4-aminophényl)-9-anthryl]aniline moiety is reported. It has been shown that the diaryldiamines possess fluorescent properties and that they were reversibly oxidized into stable di(radical cation)s.
