Abstract:

The success of homogeneous asymmetric catalysis has been attributed to the structure and stereochemistry of the coordinated ligand(s). The most effective ligands are C<sub>2</sub>-symmetrical bisphosphines containing either a rigid chiral backbone linking two PPh<sub>2</sub> units or a bisphosphine, DIPAMP containing two chiral phosphine units linked by an achiral backbone. The synthesis of P-chiral ligands of this type has been severely hindered by the lack of a general synthetic route allowing the incorporation of phosphorus chirality without the need for separation of diastereomeric precurs

Abstract:

This thesis is divided into six chapters. The first is a review of general asymmetric synthesis, and considers in detail the palladium catalysed allylic substitution reaction, the 1,4-conjugate addition and the Heck reaction. The second deals with our general synthetic approach to the chiral ligands. Here we synthesized a range of ligands derived from chiral amino alcohols condensed with aryl and aliphatic ketones. We also synthesized chiral sulphur imine and phosphorus imine ligands. The third deals with applications of the ligands in the above reactions, and discusses the most successful lig

Abstract:

For the purpose of incorporating indoles into organometallic complexes for catalysis, as well as in the generation of new heterocyclic systems, various reactions have been carried out at C2, C6 and C7 of the indole system. In order to achieve this, 3-substituted 4,6-dimethoxyindoles and 6-hydroxy- 4-methoxyindoles were necessary as starting materials. Consequently, a lithium-bromide-templated one-pot procedure for the synthesis of some 3-substituted 4,6-dimethoxyindoles and a selective demethylation procedure for 3-substituted 6-hydroxy-4-methoxyindoles were developed. Various kinds of novel

Dual activation by means of this system was probed in cyanide addition to aldehydes.

In this manner, between two and six such groups have been attached to a benzene ring to give ligands which display a great variety of modes of coordination to transition metals.

Abstract:

Two new general synthetic routes to phosphines were developed. The first method described directly converts phosphonates to phosphine oxides using organometallic nucleophiles. This reaction proceeds through a five-coordinate phosphorus intermediate. The second synthetic method uses a deprotonated secondary phosphine oxide for nucleophilic addition to an alkyl halide to form a tertiary phosphine oxide. This reaction proceeds through a standard SN2 mechanism, however in extreme cases a competitive electron transfer reaction was observed. These syntheses were used to make a new dimethyl phosph

This thesis describes the development of new catalytic systems based upon iron complexes and their reactivity toward ethylene.

Those complexes were obtained either by reaction of the monoanionic ligand with FeCl3 or through oxidation of the iron(II) complex. The second reaction led to binuclear complexes. Then, another aim of the thesis was to design new well-defined cocatalysts for the activation of iron complexes. The study of the reaction between an alcohol and the trimethylaluminum allow

We report the synthesis and application of some ion-tagged catalysts in organometallic catalysis and organocatalysis. With the installation of an ionic group on the backbone of a known catalyst, two main effects are generally obtained. i) a modification of the solubility of the catalyst: if judicious choice of the ion pair is made, the ion-tag can confer to the catalyst a solubility profile suitable for catalyst recycling. ii) the ionic group can play a non-innocent role in the process considered: if stabilizing interaction between the ionic group and the developing charges in the transition

Abstract:

Il existe un grand nombre de ligands très efficaces actuellement employés pour la catalyse d’hydrogénation (BINAP, MeO-BIPHEP) et de couplage (S-PHOS, ligands PAP). La plupart d’entre eux possède une symétrie C2. Au cours de la thèse, nous avons étudié l’influence de la symétrie C1 sur les performances catalytiques de mono- et de diphosphines possédant une structure biaryle ou hétéro aromatique/ aromatique. Nous avons également étudié l’influence de leurs propriétés stériques et électroniques. Ces structures ont, pour la plupart, été obtenues par couplage aryne suivi par des réactions d’échang

Abstract:

The dinuclear cyclometallated gold(I) complex [Au2(μ-2-C6F4PPh2)2] was prepared in high yield from the reaction of 2-LiC6F4PPh2 with either [AuBr(AsPh3)] or [AuCl(tht)], and from the reaction of 2-Me3SnC6F4PPh2 with [AuCl(tht)]. The digold(I) complex undergoes oxidative addition reactions with halogens to give the metal-metal bonded dihalodigold(II) complexes [Au2IIX2(μ-2-C6F4PPh2)2] (X = Cl, Br, I), which on warming or exposure to light, isomerise to give the heterovalent gold(I)-gold(III) species [XAu(µ-2-C6F4PPh2)(κ2-2-C6F4PPh2)AuX] containing a four-membered cyclometallated ring on a

Abstract:

The luminescence properties of cyclometallated iridium(III) complexes render them of interest, for example, as phosphorescent dopants in organic light-emitting devices (OLEDs), as photoactive units in solar energy conversion, and as biosensors. The vast majority comprise three bidentate ligands, archetypal examples being Ir(ppy)3 and [Ir(ppy)2(bpy)]+ (ppy = 2-phenylpyridine; bpy = 2,2'- bipyridine). The work described here explores the chemistry of iridium(III) complexes that contain a terdentate cyclometallating ligand. Most of the complexes studied have the general formula Ir(N^C^N)(N^C)X, w

Abstract:

The catalytic asymmetric oxidation of alkenes has special interest from both industrial and academic points of view. For this reason, catalysts able to perform these reactions in a faster and more effective manner have been developed along the latest years. This thesis describes the synthesis of new N-donor ligands (one bidentate, one bridging tetradentate and a family of spiro tetradentate), some of them chiral. The coordination of these ligands to different manganese salts is also described, giving mono-, bi- and pentanuclear complexes that have been fully characterized through structural, s
