Abstract:

Phosphate ester linkages are omnipresent in nature and are found in many biologically important molecules such as DNA, RNA and ATP. Many enzymes that hydrolyze phosphate esters are activated by metal ions. Since the structure of biological enzymes can be quite complicated, it is often useful to work with simpler artificial metalloenzymes to help elucidate the mechanisms by which phosphate ester hydrolysis is activated by metals.<br>In principle, simple dinuclear metal complexes could hydrolyze phosphate esters by double Lewis acid activation or by a combination of single Lewis acid activation

The homogeneous hydrogenation of esters and related compounds has been achieved by a catalyst-generated in-situ from the precursors Ru(acac)(_3) and the tripodal phosphine ligand l,l,l-tris(diphenylphosphinomethyl)ethane (Triphos). The catalyst is susceptible to deactivation in the presence of primary alcohols by their dehydrogenation to an aldehyde, which is subsequently decarbonylated to produce the [Ru(Triphos)H(_2)(CO)] complex, characterised by (^1)H and (^31)P NMR spectroscopy, elemental analysis, IR and X- ray crystallography.

Chapter 2 describes studies on the hydrogenation of 2,3-benzofuran.

Abstract:

La catalyse de l'addition directe du formiate de methyle sur l'ethylene pour obtenir selectivement du propionate de methyle en presence de complexes du palladium a ete etudiee. Le precurseur dichlorobis tri(n-butyl) phosphine palladium a permis de generer une espece active palladium-hydrure par reaction avec le borohydrure de sodium et un leger exces de tri(n-butyl) phosphine. Ce systeme catalytique a permis d'obtenir une activite correcte et une tres haute selectivite dans l'ester attendu. Un cycle catalytique a ete propose. La synthese de plusieurs complexes contenant le groupement carbometh

Abstract:

La fonctionnalisation regioselective de l'acrylate d'ethyle en methylmalonate correspondant peut realisee par une reaction en deux etapes mettant en jeu un complexe hydruroanionique, khfe(co)#4. Toutefois, la reaction n'est pas catalytique et les rendements sont faibles. Cette reaction a ete optimisee puis etudiee afin de comprendre les mecanismes mis en jeu et d'essayer de mettre au point un processus catalytique. Toutefois, les essais catalytiques se sont reveles infructueux. L'analyse des raisons de cet echec a conduit a envisager l'hydrocarboxylation catalytique de sels de l'acide acryliqu

La these decrit la reaction d'hydroesterification catalytique de l'ethylene par le formiate de methyle en presence de complexes du ruthenium carbonyle dopes par divers promoteurs anioniques. Le manuscrit debute par une etude bibliographique exhaustive des principaux systemes catalytiques mettant en jeu un promoteur halogene. La reaction d'hydroesterification est ensuite abordee par une etude comparative de l'efficacite de divers promoteurs associes a ru#3(co)#1#2: halogenures, acetate, alkoxyde (ion pyridonate), amidure (anion derive de l'anilinopyridine) sont evalues.

Abstract:

La production d'esters par hydroesterification consiste en l'addition directe de formiate de methyle sur des alcenes. Cette reaction se substitue a l'alcoxycarbonylation qui emploie un melange de methanol et de monoxyde de carbone. La reaction est catalysee par des complexes du ruthenium tels que ru#3(co)#1#2 et ru#3(co)#1#0(ch#3cn)#2. La presence de solvants polaires est essentielle a la generation de systemes catalytiques actifs. Ainsi a 170c et sous 25 bars d'ethylene, ru#3(co)#1#2 solubilise dans l'acetonitrile permet d'atteindre des rendements en propanoate de methyle de pres de 70% avec

Abstract:

Ce travail porte sur l'utilisation de complexe du palladium (0) en catalyse homogène pour la synthèse de molécules d'intérêts biologiques. Trois applications y sont décrites: - la synthèse d'une phéromone secrétée par la reine des abeilles et d'une hormone végétale : l'acide traumatique. La construction du squelette carbone de ces molécules est basée sur une double alkylation d'une bis (aryl sulfonyl) méthane, l'une d'entre elles faisant intervenir un complexe eta (3) allyl palladien fonctionnalisé ; - la synthèse d'alpha-amino esters susceptibles d'être utilisés comme inhibiteur d'enzyme.

Abstract:

La synthèse d'esters par carbonylation de dérivés halogénés en présence de formiates d'alkyle et de catalyseurs à base de palladium a été étudiée. Il a pu être montré que lorsque la base utilisée dans cette réaction était de la triéthylamine, le méthanol présent initialement dans le formiate de méthyle ou produit par décarbonylation de ce dernier, jouait un rôle prépondérant. Après avoir mis en évidence les difficultés occasionnées par un transfert direct de l'entité méthoxycarbonyle du formiate vers le substrat, nous avons développé un système utilisant un alcoolate en tant que base.
