Fonctionnalisation du phosphore blanc pour la synthèse de nanoparticules de phosphures métalliques et d'organophosphines

Abstract : This manuscript presents an original synthesis of nickel(0) nanoparticles. The use of a nickel(II) dioleylamide precursor results in a versatile, robust, water-free method for the production of size-tunable particles between 4 - 11 nm in diameter. This method was extended to form small iron(0) and cobalt(0) nanoparticles. These particles were examined for catalytic activity, including the hydrosilylation of a terminal alkene, the selective hydrogenation of phenylacetylene to styrene, and the substoichiometric reduction of nitrogen to tris(trimethylsilyl)amine. White phosphorus (P4) was stoichiometrically reacted with the metal(0) nanoparticles to form the corresponding metal phosphide nanoparticles. White phosphorus was alternatively functionalized using superhydride (LiBEt3H) to form a borane-stabilized phosphanide species, LiPH2(BEt3)2. This species was used to synthesize various phosphines, including phosphine, tris(trimethylsilyl)phosphine, and triaroylphosphines. The labile triethylborane adducts were replaced by BH3, resulting in the formation of LiPH2(BH3)2, which may have applications in the formation of P-B polymers.
