Synthèse, caractérisation et étude de l'activité catalytique de complexes organométalliques du rhodium dans la réaction de silylation déshydrogénante des oléfines

Abstract : This work concerns the synthesis of new homo- and heterobinuclear organometallic rhodium complexes using s-indacene as a bridging ligand, together with the determination of their efficiency in the catalytic system of the dehydrogenative silylation of olefins. After a short introduction about the importance of catalysis, the second chapter describes an extensive synthetic procedure to produce poly-substituted-1,5-dihydro-s-indacenes, and their characterization by NMR (1H, 13C, mass spectrometry) and EPR spectra of their anion radical. The synthesis of different mononuclear, homo- and heterobinuclear complexes are then described, and characterized by classical tools (NMR, mass spectrometry) and also ESR reactions and cyclic voltammetry experiments. The behavior the catalysts previously synthesized in catalysis, more particularly in the Dehydrogenative Silylation of olefins have also been described.
