Synthèse d'aryl et de polyarylamines par catalyse au nickel pour le développement de nouveaux matériaux conducteurs

Abstract : This work describes the preparation of new nickel catalysts for C-N cross coupling reactions and the physicochemical caracterisation of new polyarylamines synthetised. In a first part, the Ni(0)/bpy catalyst was used for the synthesis of di- and triaminobenzenes from aryl chlorides. Among products prepared, 1,3,5-tris[4-aminophenyl]benzenes showed a original electrochemical behaviour and the formation by oxidation of charge transfert complexes was demonstrated. In the second part, the development of a new nickel catalyst, noted Ni(0)/SIPr in which nickel is coordinated by a N-heterocyclic carbene is described. Contrary to the Ni(0)/bpy catalyst, the Ni(0)/SIPr reagent is efficient for the arylation of all classes of amines. The synthesis of new naphthidines using the Ni(0)/SIPr catalyst, and their oxidation into stable di(radical cation) is finally reported.
