Texto completoThe present work is an organometallic study concerning the chemistry of gold(I) complexes and their reactivity. Of particular interest was to gain further knowledge on the impact of the ligands employed on the reactivity of gold towards (i) the intermolecular oxidative addition of aryl halides and (ii) the possibility of stabilizing high reactive gold(I) intermediates. In the first part of the manuscript, the intermolecular oxidative addition of aryl halides (iodide and bromide) with molecular gold(I) complexes was investigated in detail. We showed that this organometallic elementary step, usually considered to be impossible for gold, is actually a favorable process when an adequate ligand is employed and two different strategies have been elaborated. The first one consists in the use of a bis-phosphine bidentate ligand that forces a bent geometry around gold, whereas the second strategy implicates the use of a hemi-labile bidentate ligand bearing a soft and a hard donor group. Both strategies were found fruitful, and the gold(III) complexes stemming from oxidative addition reactions were characterized by spectroscopic and structural means. In the second part, having in hands two gold(I) complexes that undergo the oxidative addition reaction, we wanted to go beyond this elementary step. In that objective, we constructed a new Au(I)/Au(III) catalytic cycle involving a sequence of Csp2-X oxidative addition, Csp2-H auration and reductive elimination, allowing the first example of gold-catalyzed direct arylation of arenes with aryl halides. Finally, in the last part, we attempted to stabilize and characterize high reactive gold(I) intermediates, like the a-oxo gold(I) carbenes. This electrophilic species is proposed in many catalytic transformations as key intermediates, but has never been isolated or characterized (in solution or in solid state). The use of a bidentate diphosphine ligand allowed the characterization of the a-oxo gold(I) carbene for the first time by means of multinuclear NMR spectroscopy, X-ray diffraction analysis and high resolution mass spectroscopy (ESI+). We then investigated the reactivity of the a-oxo gold(I) carbene towards insertion and cyclopropanation reactions. Interestingly, the reactivity of the generated gold(I) carbenes can be modulated depending on the electronic properties of the aryl ethyl diazoacetate used

Texto completoThe activation of C-H bonds has emerged as an attractive approach for advancing the synthesis of novel heterocyclic systems with potential applications across diverse fields, particularly in biology and pharmacy.The primary aim of this PhD thesis was to develop innovative strategies for the selective functionalization of nitrogen-containing heterocycles through C-H activation reactions, employing transition metal catalysis.In the first part, we developed a synthesis methodology enabling the regioselective functionalization at the ortho position of the N-oxide function in 7-azaindazole derivatives. The reaction goes through anoxidative arylation reaction, with various arenes and heteroarenes as coupling partners. This approachenables precise control over the position of functionalization through optimized reaction conditions, which is crucial to design new compounds with enhanced properties whatever the domains of application.In the second part of our research, we conducted a series of experiments to perform a regioselectiveoxidative alkenylation on the pyridine moiety of 4-azaindazole and 7-azaindazole. Using the N-oxidefunction as an ortho directing group allowed us to exert control over the position of functionalization.In the last part, we presented our work aimed at establishing optimal conditions for a direct arylation reaction on various 7-azaindazole analogues. The use of the N-oxide function favoured the regioselectivity of the reaction towards the C6 position

Texto completoThe present work deals with the synthesis of Au(III) and Cu(III) compounds and the study of their stability and reactivity toward p substrates. An experimental and theoretical approach has been used in order to access complexes capable of undergoing migratory insertion processes. The first chapter delivers a bibliographic overview of the organometallic chemistry of gold and copper. The importance of the high oxidation state +III is highlighted by the description of important examples having contributed to the understanding of processes associated to the access and reactivity of Au(III) and Cu(III) complexes. The second chapter describes the synthesis of two p-arene Au(III) complexes by migratory insertion of olefins in the Au-C(sp)2 bond of a (P,C) cyclometallated complex. Interactions between the metallic center and the aromatic systems have been characterized by NMR, DFT and XRD for one of the complexes. Based on this insertion reactivity, a process of direct arylation of ethylene has been evidenced. The third chapter concerns the development of an intermolecular hydroarylation of alkynes process, catalyzed by [(P,C)Au(III)(OAcF)2] complexes. These have shown great activity and robustness in presence of trifluoroacetic acid. The reaction has been generalized to a broad substrate scope and a comparative study has been carried on, especially with (N,C) cyclometallated complexes, showing the superiority of (P,C) complexes for the hydroarylation of alkynes. The fourth chapter presents the envisioned strategy to develop a copper-catalyzed oligomerization of ethylene process. A predictive approach based on DFT calculations permitted to evidence easier migratory insertions in the Cu(III)-C bond than in the Cu(I)-C bond. Two strategies for the access to Cu(III) species have been theoretically evaluated. The most favourable calculations have oriented the choice of ligand models used in chapters five and six. The fifth chapter deals with the experimental study related to the first strategy of access to Cu(III) species: the directed intramolecular oxidative addition by peri-iodo napthylphosphine and naphthylamine ligands.
