Abstract:

The work in this thesis consists of three related studies. (i) Further investigations have been made into the mechanism of the photochemical reaction between (Mn[sub]2(CO)[sub]8{PBu[sub]3}[sub]2) and benzyl halides, equation 1. A previous study in these laboratories, which included an (Mn[sub]2(CO)[sub]8{PBu[sub]3}[sub]2) + PhCH[sub]2Cl -->(MnCl(CO)[sub]4PBu[sub]3) + (Mn(PhCH[sub]2)(CO)[sub]4PBu[sub]3) 1 examination of reaction kinetics, led to the suggestion that the mechanism involved CO dissociation from the manganese dimer, followed by metal-metal bond homolysis and subsequent reaction of the 15-electron intermediate, (Mn(CO)[sub]3PBu[sub]3, with benzyl chloride. The present work begins with the realisation that the previous data is also compatible with a radical chain process. In an attempt to distinguish between these two mechanisms, studies have been make of the variation in the quantum yield for the formation of (MnCl(CO)[sub]4PBu[sub]3) with benzyl chloride concentration. An examination of the reaction between (Mn[sub]2(CO)[sub]8DPPM) and benzyl chloride has also been carried out. Unfortunately, these studies still do not provide an unambiguous distinction between the mechanisms. (ii) A study has been made of the thermal reaction between (Mn[sub]2(CO)[sub]8a{PBu[sub]3}[sub]2) and benzyl and other halides. At 40 C the reaction is first order in both manganese dimer and benzyl choride and is not inhibited by added CO. This contrasts with that previously reported for the photochemical reaction and indicates that the thermal reaction follows a different pathway. Reaction of the metal dimer with 6-bromo-hex-1-ene suggests a free radical process and reactions with substituted benzyl bromides indicate an electron transfer step. Thus a mechanism is proposed involving electron transfer from the dimer to the organic halide, as the first step. Subsequent fission of the radical anion so formed into a halide ion and an organic radical, such as PhCH2, is followed by reaction of the dinuclear radical cation with the halide ion generating (MnCI(CO)[sub]4PBu[sub]3) and (Mn(CO)[sub]4PBu[sub]3). The manganese-centered radical then combines with the benzyl radical to yield (MnBz(CO)[sub]4PBu[sub]3). This reaction is thus a non-chain process. (iii) In view of the findings detailed above that (Mn[sub]2(CO)[sub]8{PBu[sub]3}[sub]2) reacts with benzyl chloride according to equation 1, it was deemed appropriate to examine the reactions between benzyl halides and a range of dinuclear metal complexes. The complexes studied were (M[sub]2(CO)[sub]10) (M = Mn, Re), (Mo[sub]2(CO)[sub]6Cp[sub]2), (Fe(CO)[sub]2Cp)[sub]2, (Fe[sub]2(CO)[sub]3PBu[sub]3Cp[sub]2), (Fe(CO){P(OMe)[sub]3}Cp)[sub]2 and (Co[sub]2(CO)[sub]6{PBu[sub]3}[sub]2), (Cp = D[sup]5-C[sub]5H[sub]5). Only (Fe[sub]2(CO)[sub]3PBu[sub]3Cp[sub]2) reacted with benzyl chloride under thermal conditions. All the dimers, except (M[sub]2(CO)[sub]10) (M = Mn, Re), reacted with benzyl bromide giving the corresponding bromo-complexes. Photochemical reactions with benzyl chloride were observed for all dimers except (Co[sub]2(CO)[sub]6{PBu[sub]3}[sub]2) and all, including the cobalt complex, reacted with benzyl bromide. In all cases, halo-complexes were formed, however, the observation of the associated benzyl complexes depended on both the benzyl halide and the metal dimer.

Enfin, le problème de l'extraction liquide-liquide des lanthanides par le NIPA dans le nitrométhane a été abordé. Les résultats obtenus ont révélé que le NIPA est un excellent agent extractant, notamment en milieu nitrique, et que l'efficacité de l'extraction augmente quand le rayon atomique diminue

Includes bibliographical references.
This thesis presents nitrene transfer reactions that are catalyzed or mediated by late transition metal complexes. Sterically large, fluorinated supporting ligands are used to minimize potential side reactions. A new 1,10-phenanthroline ligand has been synthesized with 2,4,6-(CF3)3C6H2- groups in the 2- and 9-positions (1). A cationic copper(l) complex of 1 catalyzes nitrene transfer from N-(p-toluenesulfonylimino)phenyliodinane (PhlNTs) to the C-H bonds of 1,3-dimethoxybenzene in 63% yield. Altering the stoichiometry results in the formation of a different major product, N,N-bis(2',4'-dimethoxyphenyl)-p-toluenesulfonamide, in 33% yield. Treatment of a cationic copper(l) complex of 1 with p-nitrobenzenesulfonyl azide (NsN3) results in the formation of a rare mononuclear sulfonamido complex of copper(ll), 2. This complex is presumably formed via decomposition of a reactive sulfonimido complex of copper(lll). Although not a proficient nitrene transfer reagent to benzene, complex 2 is a precatalyst for nitrene transfer from NsN3 to benzene. Deprotonation of a palladium(ll) sulfonamido complex of 1 results in the formation of the first mononuclear sulfonimido complex of palladium,
(cont.) 3. The sulfonimido ligand is bound in a K2-N,O chelate. This complex is a proficient nitrene transfer reagent to carbon monoxide, phosphines, and ethyl vinyl ether. A rhodium(lll) hydride chloride complex containing two N-heterocyclic carbene ligands, one of which is cyclometallated, is a convenient synthetic equivalent of a rhodium(l) chloride complex. Treatment of the rhodium(Ill) hydride with acetonitrile results in reductive elimination to form a rhodium(l) chloride complex. The chloride is readily abstracted by sodium azide to form a cationic rhodium(l) complex coordinated by two molecules of acetonitrile and containing an unbound azide. Upon exposure to UV light, this molecule undergoes cyclometallation to form a cationic rhodium(lll) hydride complex. The rhodium(lll) hydride chloride complex can be treated with oxygen to form a rhodium(lll) peroxide complex. The neutral peroxide complex has poor reactivity with trimethylphosphite and t-stilbene. However, a cationic rhodium peroxide complex oxidizes trimethylphosphite and t-stilbene at elevated temperatures.

Abstract:

Ce travail concerne des etudes thermodynamiques et cinetiques de la complexation du fer(iii) par des ligands possedant des sites de coordination de type 8-hydroxyquinoleine et 2,2'-dihydroxybiphenyle. La premiere partie a concerne l'etude des complexes ferriques des ligands 8-hq (oxine), 5-so#3#, 8-hq (sulfoxine) et 5-f-8-hq (fluorooxine). Les resultats mettent en evidence l'influence des proprietes electroniques des sites de coordination sur la stabilite des complexes. Quand la coordination du fer par le ligand n'est pas complete, des hydroxo complexes sont formes. Les etudes cinetiques de formation et d'hydrolyse acide des complexes permettent une approche du mecanisme de formation et d'hydrolyse du complexe. Le mecanisme est exprime en terme d'une succession d'etapes de formation et de coupure des liaisons n-fe et o-fe. La seconde partie a ete consacree a l'etude thermodynamique et cinetique de la complexation de l'ion fe#3#+ avec des ligands de structure tripode o-trensox et n-trensox a sous-unites 8-hydroxyquinoleine. La caracterisation des ligands ainsi que des a permis de determiner les constantes d'equilibre et d'obtenir egalement des informations structurales a l'aide des methodes spectrophotometriques uv-vis, ir et potentiometriques. La cinetique de formation du complexe fe(o-trensox) en milieu acide ainsi que sa cinetique d'hydrolyse acide ont ete etudiees afin de mettre en evidence les mecanismes de complexation du fer par le ligand et de sa sortie de la cage de coordination formee par le ligand. Les resultats des etudes cinetiques d'echanges de l'ion fe#3#+ entre la transferrine, l'edta et o-trensox permettent de proposer un mecanisme pour l'echange du fer entre la transferrine et le ligand o-trensox. La troisieme partie concerne l'etude thermodynamique et cinetique de la complexation du fer par un ligand biphenol et son homologue tripode. Cette etude de physico-chimie en solution permet de mieux comprendre les interactions cations metalliques-ligands dans les perspectives de conception de molecules actives dans le domaine de la sante et de l'agrochimie

Abstract:

This project was launched with the aim of developing dendrimer catalysts for oxidation and reduction reactions. Poly(amidoamine) (PAMAM) and poly(propyleneimine) (PPI) dendrimers were of interest because of their well-established synthesis. Chapter 1 describes the fundamentals of dendrimers and provides a brief insight of their application in catalysis. In particular, examples of dendritic catalysts that have been previously employed as oxidation and reduction catalysts are presented. Chapter 2 presents the synthesis and characterization of silica-supported PAMAM dendrimers, their phosphomethylation with Ph2 PCH2OH, and their complexation to palladium complexes. Chapter 3 reports the application of the silica-supported PAMAM-Pd complexes to the oxidation of alkenes to methyl ketones under Wacker-type conditions as well as the use of tBuOOH as the oxidant in these reactions. Chapter 4 discusses the use of the above-mentioned complexes to catalyze the selective hydrogenation of dienes to monoolefins in the presence of H2 under mild reaction conditions. Chapter 5 presents our efforts in modifying PPI dendrimers with the salen moiety to give ligands that are coordinated to the metals Ti and V. Attempts at using the former complexes to promote the epoxidation of alkenes and the latter complexes to catalyze the epoxidation of olefinic alcohols are discussed.

Abstract:

Two independent studies have been developed in this thesis. In the first study, the reactivities of metal-alkoxide and metal-hydroxide nucleophiles are compared for cleaving phosphate diesters. In the second study, the reactivity of a dinuclear metal complex is compared to a mononuclear metal complex for hydrolyzing RNA.
Copper(II) complexes of bis(2-pyridylmethyl)amine (Cu(II)bpa), N-(2-hydroxyethyl)bis(2-pyridylmethyl)amine (Cu(II)hebpa) and N-(3-hydroxypropyl)bis(2-pyridylmethyl)amine (Cu(II)hpbpa) have been synthesized and their reactivities and mechanisms for cleaving bis(2,4-dinitrophenyl) phosphate (BDNPP) have been investigated. Cu(II)hpbpa is observed to be the most reactive (k = 7.2 $ times$ 10$ sp{-1}$ M$ sp{-1}$ s$ sp{-1}$ at 25$ sp circ$C, pH 8.8) for cleaving BDNPP followed by Cu(II)bpa (k = 2.0 $ times$ 10$ sp{-2}$ M$ sp{-1}$ s$ sp{-1}$) and Cu(II)hebpa (k = 2.0 $ times$ 10$ sp{-2}$ s$ sp{-1}$). HPLC product analyses indicated that Cu(II)hpbpa cleaves BDNPP mostly through transesterification while the complexes Cu(II)bpa and Cu(II)hebpa cleave BDNPP predominantly by hydrolysis. The differences in the mechanisms and the reactivities are explained in terms of the differences in the structures of the three copper(II) complexes.
Copper(II) complexes of 1,8-bis(1,4,7-triazacyclononyl-N-methyl)naphthalene (tntn), 1,4,7-triazacyclononane (tacn), and N-benzyl-1,4,7-triazacyclononane (btacn) have been prepared and their reactivities compared for cleaving RNA. The novel dinuclear copper(II) complex, Cu(II)$ sb2$tntn, is observed to be 200-500 fold faster per metal center than the mononuclear copper(II)complexes, Cu(II)tacn and Cu(II)btacn, for cleaving a diribonucleotide, ApA, and its cyclic phosphate intermediate, $2 sp prime3 sp prime$-cAMP. Cu(II)$ sb2$tntn (2.0 mM) reduces the half life of ApA (0.05 mM) to 50 minutes (pH 6, 50$ sp circ$C); this represents a rate acceleration of approximately 10$ sp5$ fold over the background hydroxide rate. The half life of $2 sp prime3 sp prime$-cAMP (0.05 mM) is decreased to 4 minutes in the presence of Cu(II)$ sb2$tntn (2.0 mM, pH 6, 25$ sp circ$C); this represents a rate acceleration of about 10$ sp8$ fold over the background hydroxide rate.
