Résumé :

The steroidal 1,4-diphosphines 3α- and 3β-diphenylphosphino-2a-(2'-diphenylphosphinoethyl)-5α-cholestanes and their 5H-benzo[b] phosphindole derivatives have been prepared and shown to be useful ligands in asymmetric hydrogenation reactions. Interestingly the 3α- and 3β-derivatives lead to opposing enantioselection preferences when used in these reactions. A steroidal 1,3-diphosphine, 3α-diphenylphosphino-2α-diphenylphosphinomethyl-5α-cholestane, has been prepared as a mixture containing some of the 3β-epimer. The 3α-1,3-diphosphine led to similar enantioselection in hydrogenation reactions as

Résumé :

The reactions of 1,1-diamino-2,2-diphenyl-substituted diphosphines featuring various degrees of P-P bond polarization with different alkynes were investigated. All diphosphines reacted with alkynes carrying one or two electron withdrawing carboxylic ester moieties under cleavage of the P-P bond and stereospecific phosphinyl-phosphination at the triple bond to give unsymmetrical ethane-1,2- bisphosphines. Several of the products were further converted into chelate complexes upon reaction with group-10 metal dihalides. All isolated compounds were characterized by analytical and spectroscopic dat

Résumé :

Gold Nanoclusters are of particular interest due to their many possible applications across a wide range of scientific fields. More specifically, nano-sized gold particles have potential to be used in drug delivery systems, cancer therapy and catalysis. This dissertation focuses on improving our understanding of ligated gold nanoclusters by examining the role of a variety of phosphine based ligands, novel methods to produce monodisperse solutions, and investigating the kinetics of water soluble ligated gold nanoclusters. The addition of ligands to solutions of Au have shown to produce small (<

Résumé :

Cette thèse examine les défis posés par l’accès incertain aux éléments chimiques, exacerbée par un paradigme économique linéaire de leur exploitation. L’étude se concentre sur le bore et le phosphore, dont l’utilisation et le recyclage restent sous-étudiés. Le bore, crucial dans diverses industries, nécessite des processus énergivores pour être transformé en hydroboranes actifs, utilisés en chimie fine. Deux voies existent pour leur synthèse : la méthode industrielle à partir de borate, et la réaction de BCl₃ avec un donneur d’hydrure. Utiliser H₂ comme agent réducteur pourrait améliorer ces p

Résumé :

Cyclodextrins (CDs) are cyclic oligosaccharides of various sizes containing several α-(1→4)-linked D-(+)- glucopyranose units. The commercially available ones comprise six, seven or eight glucose units, named respectively α-CD, β-CD and γ-CD. Their truncated cone-like and well-defined cavity are particularly attractive for the encapsulation of a variety of substrates. As such, they found numerous applications in many areas of chemistry. A recent development, from which the present work is inspired, consisted in covalently linking transition metals to CD cavities in order to perform and study c

Résumé :

AbstractTransition-metal–boryl complexes having a covalent B-M bond have been considered as reactive intermediates in transition-metal-catalyzed borylative transformation of organic molecules. However, monodentate, anionic boryl ligands are not appropriate for use as supporting ligands, because they readily dissociate from the metal center. Since the first reports of transition-metal complexes possessing a pincer ligand involving boron and two coordinating sidearms, the chemistry of phosphorus-tethered PBP-pincer complexes has gradually developed. This review focuses on the synthesis of PBP-pi
