The aim of my training period has been the synthesis of new chiral N-heterocyclic carbene precursors starting from camphoric diacid and the employment of imidazolium salts derived NHC as linker to dendrimers supports for organometallic catalysis. New chiral ligands are needed to develop new catalytic systems for enantioselective transformations. The new type of ligand described was developed starting from camphoric diacid, a cheap chiral molecule, following different synthetic strategies. Asymmetric functionalized chiral NHCs are readily available by methods developed and two of the precursors

The versatility of N-heterocyclic carbenes (NHCs) is demonstrated by numerous practical applications in homogeneous transition metal catalysis, organocatalysis and materials science. There remains a paucity of electropositive metal NHC complexes and so this chemistry is poorly developed with respect to that of the late transition metal and main group elements. This thesis describes the synthesis of new alkoxy-tethered NHC proligands, their use in the synthesis of reactive metal amide and metal alkyl complexes, and finally small molecule activation using these complexes.

Although known since the 1930s, organogold chemistry has been dormant until recently, primarily due to preconceptions about the inertness of gold in transformations. However, this last decade has witnessed the emergence of a Golden Age with the development of a wealth of reports on gold in a plethora of reactions. In recent years, the drive for more atom- and step-economical and environmentally friendly reactions has become a field of intense research.

Thesis advisor: Amir H. Hoveyda<br>Chapter 1 Enantioselective Conjugate Additions of Carbon Nucleophiles to Activated Olefins: Preparation of Enantioenriched Compounds Containing All-Carbon Quaternary Stereogenic Centers. Methods for enantioselective conjugate addition of nucleophiles to activated olefins generating products containing all-carbon quaternary stereogenic centers are critically reviewed. Enantioselective conjugate addition has been shown to be a powerful and concise approach to construct carbon-carbon bonds to prepare compounds containing sterically hindered stereogenic centers a

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

Se ha obtenido una nueva familia de cuatro Complejos Organometálicos Supramoleculares (SOCs) basados en pireno. Dentro de los cuales se ha desarrollado un nuevo receptor de PAH, capaz de discernir entre los diferentes PAH en función de su forma, tamaño, y número de electrones-pi. Hemos desarrollado una estrategia eficiente para la extracción de PAH, que son compuestos tóxicos y carcinogénicos, en disolventes orgánicos. Paralelamente, se han obtenido dos receptores de fulereno, capaces de adaptar su tamaño a la forma del fulereno. Debido a la mayor afinidad respecto a un fulereno específico, mo

Des ligands hydrides potentiellement bidentes (possédant un donneur N-hétérocyclique (NHC) associé à un groupement donneur éther ou amine) ainsi que des ligands tritopiques de type pinceur (possédant un groupement (NHC) flanqué de deux types de donneurs azotés différents Nimine et Namine) ont été préparés et utilisés pour la coordination de métaux de transition tels que le Ni, Cr, Cu et Ir. L’influence de la longueur de la chaine alkylée -(CH2)2- ou -(CH2)3- reliant le groupe éther ou amine au groupe hétérocyclique (NHC) a été examinée. Dans le but d’accéder aux complexes des métaux de transit
