Abstract (sommario):

This work reports the synthesis of a series of phosphine complexes of Group 9 metals, which contain cis- or trans-coordinated phosphines. The reaction of these complexes with various substrates and their application to the catalysis of organic transformations is also reported. The first section of this work describes the synthesis of the complexes [Co(PPh3)3Cl], [Co(PPh3)i(CO)iCl], [Co(PMe3)3Cl], [Co(PMe3MCO)2Cl], [Co(PPh3)iN2)H], [Co(PPh3)iCO)H], [Rh(PPh3MCO)Cl], [Rh(PMe3)i(CO)Cl], [Rh(dppe)(CO)Cl], [Rh(dppe)(CO)(mes)], [Rh(PPh2MeMCO)Cl], [lr(dppe)(CO)Br], [lr(PPh3)i(CO)Cl], and [lr(PPh2Me)

Abstract (sommario):

The homogeneous hydrogenation of arenes with functional groups was studied with allylcobalt complexes containing the bulky chelating diphosphines dippp (1,3-bis(diisopropylphosphino)propane and dippcyp (trans-(±)-l,2-bis(diisopropylphos-phino)cyclopentane). The results indicated that these catalyst precursors were unsuitable for the hydrogenation reactions, being too sensitive to the nature of the substrate. From these hydrogenation reactions, the intermediates (η⁵-cyclohexadienyl)Co(dippcyp) (10) and (η⁴-2-methoxynaphthalene)Co(H)(dippcyp) (11) were isolated and structurally characterized, th

Abstract (sommario):

This thesis presents the first systematic study of the cobalt site preferences in iron rare-earth based compounds. The Mossbauer source technique employed in this work offers a direct and unambiguous way to quantitatively determine cobalt site preferences in these compounds at extremely low cobalt contents. Data quality as well as counting efficiency for the source ($ sp{57}$Co doped) samples is enhanced by constructing a resonant conversion electron detector utilising 90% $ sp{57}$Fe enriched stainless steel foil. Our results have produced the most convincing evidence that cobalt substitutes

Abstract (sommario):

The tricobalt cluster PhCCo3(CO)9 (1) reacts with the bidentate phosphine ligand 2,3-bis(diphenylphosphino)maleic anhydride (bma) in the presence of added Me3NO to give the diphosphine-substituted cluster PhCCo3(CO)7(bma) (2). Cluster 2 is unstable in solution, readily losing CO to afford Co3(CO)6[(μ2-η2/η1-C(Ph)C=C(PPh2)C(O)OC(O)](μ2-PPh2) (3) as the sole observed product. VT-31P NMR measurements on cluster 2 indicate that the bma ligand functions as both a chelating and a bridging ligand. At -97 °C, 31P NMR analysis of 2 reveals a Keq of 5.7 in favor of the bridging isomer. The bridged bma c

Transition metal compounds such as Co₂(CO)₈ have often been used to catalyze various organic reactions. Severe difficulties may be encountered when attempts are made to recover and separate the soluble catalysts. A heterogeneous system consisting of Co₂(CO)₈ impregnated on zeolites with faujasitic structure has been designed and investigated using a variety of techniques.

Abstract (sommario):

In order to meet the ever-increasing demand for energy, a worldwide transition away from fossil fuels to renewable solar–fuels is required. However, the intermittency of local insolation mandates a cost-effective and efficient storage scheme. Using solar-derived electricity to drive the thermodynamically uphill water splitting reaction to generate dihydrogen and dioxygen is one promising method of storing solar energy in fuels. This “artificial photosynthesis” scheme requires the execution of two half-reactions, one involving the oxidation of water to O2—the oxygen evolution reaction (OER)—and

Heusler compounds are cubic intermetallics with a wide range of interesting properties, which are closely related to the structure of the material. In addition, several exotic physical phenomena have been predicted for different compositions in the family, but have not been experimentally realized. By and large, the lack of success in realization of various properties are due to the issues with intrinsic material attributes, which have been difficult to resolve as the relationship between them is not well understood.

Magnetic properties of cobalt clusters (20 N 200) were studied in molecular beams. The magnetization of cobalt clusters is studied at a broad range of temperatures, magnetic fields and clusters sizes. It is shown that the agnetization of ferromagnetic clusters in a cluster beam can be understood as an adiabatic process using the avoided crossing theory. Besides the ground state that bears magnetic moment of about 2 Bohr magneton per atom, an excited state that has 1 Bohr magneton per atom was discovered for every cobalt cluster observed.

Abstract (sommario):

Ce travail porte sur la synthèse, la caractérisation et l’évaluation en catalyse de réduction des protons en dihydrogène, de nouveaux complexes de Ni(II), Co(III), Cu(II) et Pd(II) basés sur des ligands de type thiosemicarbazone. La nature de l’espèce catalytique active a été étudiée par voltampérométrie cyclique et des propositions de mécanisme ont été formulés sur la base de calcul quantique de type DFT.Le premier chapitre introduit le contexte scientifique. Le second chapitre concerne la synthèse et la caractérisation des ligands de type N2S2 et des complexes mononucléaires associés de Ni,
