Réactivité de complexes de métaux riches : activation de petites molécules, synthèse de nanoparticules et catalyse de couplage croisé

Abstract : The synthesis of organic compounds by green methods and at moderate cost is a major challenge. The use of organometallic complexes that allow the approach and the reaction of various substrates is an attractive solution. This study deals with complexes formed by group 10 metals, stabilized by diphosphine ligands, particularly the formation of highly reactive reduced species. Activation of white phosphorus is presented, and this approach is extended to the synthesis of metal phosphides nanoparticle, obtained from metallic nanoparticles. Finally, a well-defined nickel (0) complex is used to activate carbon dioxide, C H bonds, or to catalyze cross-coupling reactions (Negishi type), quite remarkable results.
