Abstract:

This doctoral thesis focuses on the synthesis of new ligands and their application in two types of catalytic process: a) palladium catalysed carbonylation reactions and b) asymmetric reactions (hydrogenation of challenge substrates and C-C bond formation). In the first part of the thesis, the synthesis of a family of new diphosphine ligands and their application in Pd-catalysed carbonylation processes is described. These ligands were first used in the Pd-catalysed methoxycarbonylation of ethane, achieving high activity and selectivity. A mechanistic study on these catalytic systems reveale

Abstract:

Photovoltaic cells and fluorescence sensing are two important areas of research in chemistry. The combination of photon-activated electron donors with electron acceptors provides a strong platform for the study of optical devices. A series of four oligothiophene-ruthenium complexes has been synthesized. Variation in oligothiophene length and bipyridine substitution allowed comparison of these variables on electronic properties. The longer oligothiophenes display lower energy absorption and emission compared to the shorter ones. Aromatic conjugation appears more complete with para-, rather than

Abstract:

Les complexes carbéniques ont connu un essor considérable ces dernières années. L'introduction générale présente les différentes facettes de ces complexes aux propriétés aussi diverses qu'uniques. D'abord utilisés comme réactifs stoechiométriques, les complexes carbéniques sont devenus des catalyseurs de choix dans de nombreuses réactions. Dans ce contexte, nous présenterons différentes approches pour la synthèse de complexes carbéniques hétérosubstitués.<br /><br />Le premier chapitre présente la synthèse et la chimie de coordination d'aminoarylcarbènes possédant un squelette biphényl ou bina

Abstract:

By examining structure activity relationships for a given catalytic reaction it is possible to discover what ligand features and parameters lead to stable and highly active/selective catalyst systems. With this knowledge in hand it may be possible to rationally design next generation ligands and catalysts to affect improved substrate transformations, with higher selectivities and faster reaction times. The success of Burk's DuPhos ligands in asymmetric hydrogenation demonstrated that chiral phosphacycles can be a potent source of chiral induction, whilst in a similar vein the work of van Leeuw
