Abstract:
A series of methylpalladium(II) complexes with pyrimidine-NHC ligands carrying different aryl- and alkyl substituents R ([((pym)^(NHC-R))PdII(CH3)X] with X = Cl, CF3COO, CH3) has been prepared by transmetalation reactions from the corresponding silver complexes and chloro(methyl)(cyclooctadiene)palladium(II). The dimethyl(1-(2-pyrimidyl)-3-(2,6-diisopropylphenyl)imidazolin-2-ylidene)palladium(II) complex was synthesized via the free carbene route. All complexes were fully characterized by standard methods and in three cases also by a solid state structure.

Abstract:
L’objectif de cette thèse portait sur la synthèse de complexes portant un ligand NHC associé à une fonction oxygénée et à leur application en catalyse d’oligomérisation de l’éthylène. Dans le but de synthétiser des complexes avec des ligands NHCalcool, les complexes d’argent correspondants ont été synthétisés et utilisés en transmétallation. Aucun résultat concluant n’a pu être obtenu avec le nickel à cause de l’acidité du proton alcoolique. Mais un ligand NHC-alcoolate a pu être obtenu par déprotonation directe du pro-ligand avec une base forte. Il fut alors possible d’accéder à des complexes

Au début du deuxième chapitre, le nouveau concept est présenté. Celui-ci repose sur la formation d’un axe de chiralité qui est créé lors de la coordination du ligand NHC à un métal de transition.

La catalyse asymétrique en général et la réaction de Suzuki-Miyaura asymétrique en particulier s'inscrivent dans cette démarche. Notre projet s'axe dans cette thématique, dans l'optique de développer de nouveaux catalyseurs chiraux pour la réaction de Suzuki-Miyaura asymétrique. Deux familles de complexes de palladium à ligands ferrocéniques chiraux bifonctionnels NHC/phosphine et NHC/amine ont été développés. La première famille de complexes a été synth

The first part is focused on studies of N-heterocyclic carbene (NHC) palladium(IV) intermediates, which are involved in oxidative addition mediated C-C, and C-O bond formation processes as well as in C-Cl bond forming reactions via a reductive elimination process. Bis-NHC-Pd(II) complexes have been reported as effective catalysts to mediate direct conversion of methane into methanol. However, a H-D exchange study revealed that the bis-NHC-Pd(II) complexes are not the active species r

Chapter two covers the design and synthesis of a range of tethered N-heterocyclic carbene (NHC) complexes of Pd. In addition, the syntheses of a number of new tethered NHC ligands are described. The use of Density Functional Theory (DFT) to model the complexes in this thesis was explored. Chapter three describes the synthesis
