Résumé :
Single crystals of the isotypic hydrides Ba2H3X (X = Cl or Br) were obtained by solid-state reactions of Ba, NaCl, NaNH2 and metallic Na, or Ba, NH4Br and Na, respectively, in sealed, silicajacketed stainless-steel ampoules. The crystal structures of the new compounds were determined by means of single crystal X-ray diffraction. Ba2H3Cl and Ba2H3Br crystallize in a stuffed anti CdI2 structure and adopt the space group P3̄m1 (No. 164) with the lattice parameters a = 443.00(6), c = 723.00(14) pm and a = 444.92(4), c = 754.48(14) pm, respectively. The hydride positions are derived by crystallographic reasoning and with the help of EUTAX calculations. The results are compared with known data for binary and ternary alkaline earth metal hydrides.

Résumé :
Abstract The dream of realizing room temperature superconductivity is one of the most challenging problems in condensed matter physics. Currently, materials with dense hydrogen contents at high pressures hold great promise for realizing room temperature superconductivity. In particular, pressurized alkaline earth metal hydrides received particular attention following the recently predicted sodalite-like calcium hydride (CaH6) with predicted Tc about 261 K above a pressure of 150 GPa; and magnesium hydride (MgH6) with predicted Tc about 270 K above 300 GPa. In this paper, we studied magnesium hydride (MgH4) with tetragonal (I4/mmm) type symmetry, and we found that this structure shows the highest T c ≅ 313 K at a pressure of 280 GPa which is higher than that of MgH6. Using density-functional perturbation theory (DFPT), the superconducting transition temperature, electron-phonon coupling, Eliashberg spectral function, and the logarithmic average frequency were computed. Our results reveal that, the computed values are reasonably in agreement with previous estimates.

Résumé :
Due to their extensive present, important and versatile potential applications, metal hydrides (MH) are among the most investigated solid-state systems. Theoretical, numerical and experimental studies have provided a considerable knowledge about their structure and properties, but in spite of that, the basic electronic principles of various interactions present in MH have not yet been completely resolved. Even in the simplest MH, i.e. alkali hydrides (Alk-H), some trends in physical properties, and especially their deviations, are not well understood. Similar doubts exist for the alkaline-earth hydride (AlkE-H) series, and are even more pronounced for complex systems, like transition metal-doped AlkE-H, alanates and borohydrides. This work is an attempt of explaining some trends in the physical properties of Alk-H and AlkE-H, employing the Bader analysis of the charge distribution topology evaluated by first-principle all-electron calculations. These results are related to some variables commonly used in the explanation of experimental and calculated results, and are also accompanied by simple tight-binding estimations. Such an approach provides a valuable insight in the characteristics of M-H and H-H interactions in these hydrides, and their possible changes along with external parameters, like temperature, pressure, defect or impurity introduction. The knowledge of these basic interactions and processes taking place in simple MH are essential for the design and optimisation of complex MH-systems interesting for practical hydrogen storage applications.

Résumé :
Metal dodecahydro-closo-dodecaborates have been recently explored as materials for hydrogen storage and as promising ionic conductors. However, their utility as hydrogen storage media is impeded by their high thermal stability, kinetic limitations, and side reactions. The high thermal and chemical stability of these materials makes them interesting for solid battery membrane applications, however more work is needed to understand the complicated phase transitions which occur in many metal dodecahydro-closo-dodecaborates. Recent literature suggests that dodecahydro-closo-dodecaborate species are formed as stable intermediates during the dehydrogenation of metal borohydrides [1]. This hypothesis is especially intriguing in the context of high thermal stability reported for compounds containing icosahedral dodecahydro-closo-dodecaborate anions in the presence of hydrogen gas [2]. Here, a series of multi-component alkali, alkaline-earth and transition metal [B12H12]2- compounds were isolated and characterized by single-crystal and powder X-ray diffraction techniques. Attempts to rehydrogenate M2B12H12 and MB12H12 (where M= alkali or alkaline-earth metal) in the presence of the metal hydrides we made, and several compounds were found to be susceptible to dehydrogenation/rehydrogenation reactions. In addition, selected M2B12H12 compounds were found to display high-temperature phases with increased values of alkali metal ionic conductivity.

In this project the evolution of resistivity under light exposition in materials like rare earth metal-oxy-hydrides is studied. These materials observe a decrease of the resistance when exposed under the light of a 19,5 W power lamp, and slowly tend to return to their initial resistance. After having developed a resistance measurement setup, the photoconductivity of different samples (Gd, YHO) was measured in function of the oxygen concentration and in different conditions such as the face of illumination.

Résumé :
Cette recherche visait à étudier les applications potentielles des complexes d'hydrure de Mg et de Ca soutenus par des ligands ß-diketiminate et amidinate pour la réduction des molécules de CO2. Les capacités catalytiques de ces complexes ont été explorées dans le contexte de l'hydroboration et de l'hydrosilylation du CO2. Dans la première partie de l'étude, nous avons examiné la réactivité des hydrures ß-diketiminato de Mg et de Ca avec le CO2. Il a été observé que le complexe d'hydrure de Mg incorporait rapidement le CO2, conduisant à la formation de divers intermédiaires avec différentes nucléarités. Cela implique l'insertion de la liaison Mg—H dans le CO2, ce qui entraîne la génération de groupements formate. Sous l'effet de la chaleur, des complexes de formiate hexamériques ont été formés par un mécanisme de "retournement de ligand", libérant les entraves stériques autour des centres métalliques. Pour les réactions à l'hydrure de Ca et au CO2, l'analyse RMN in situ a été principalement réalisée. En outre, un nouveau complexe amidinate dihydride de Mg a été synthétisé avec succès et a réagi avec du CO2 pour donner un produit unique de complexe formate Mg dimérique, contrairement à l'échafaudage ß-diketiminate, où plusieurs espèces de formate ont été détectées. La deuxième partie de la recherche s'est concentrée sur l'hydroboration catalytique du CO2 à l'aide de complexes d'hydrures alcalino-terreux. En particulier, le système à base de Ca a démontré une grande efficacité dans la production de la réduction à quatre électrons du CO2 ou du produit BBA. Il s'agit du premier exemple d'utilisation de composés hydrides de Mg et de Ca pour catalyser l'hydroboration du CO2, produisant sélectivement le produit BBA. Le BBA généré in situ a ensuite été utilisé comme réactif de transfert de méthylène dans des réactions de condensation avec des thiols, ce qui a entraîné la formation de nouveaux composés hémithioacétals stables [RS—CH2—OBR2] dans des conditions douces et neutres. L'activation des composés hémithioacétals a été réalisée dans des conditions acides, conduisant à la formation de dithioacétals et d'hémithioaminals. La condensation du deuxième fragment OBR2 avec des amines secondaires, qui agissent comme des nucléophiles plus puissants, a abouti à la génération de sulfures d'aryle et de méthyle [RS—CH2—NR2]. Dans la dernière section, nous avons étudié l'hydrosilylation en tandem du CO2 en utilisant divers hydrosilanes en combinaison avec des complexes d'hydrures à base de [Ae] et l'acide de Lewis B(C6F5)3 comme catalyseurs. Cette recherche a élargi les études précédentes sur l'hydrosilylation du CO2 médiée par le Mg et a introduit le premier exemple d'hydrosilylation du CO2 catalysée par le Ca avec des hydrosilanes. L'efficacité de la réduction du CO2 en CH4 ou en bis(silyl)acétal [H2C(Ph3SiO)2] ou en BSA dépend de la nature des silanes et des encombrements stériques autour de la liaison Si—H du substrat. Le choix du catalyseur [Ae] a également influencé de manière significative la vitesse globale de la réaction. En outre, les analyses d'Eyring et d'Arrhenius ont permis de mieux comprendre les paramètres d'activation de la réduction du CO2 par certains catalyseurs, révélant que cette réaction est principalement régie par une contribution entropique. En résumé, cette recherche a démontré la réactivité des complexes d'hydrure de Mg et de Ca pour la réduction du CO2 et a exploré leurs applications dans les réactions d'hydroboration et d'hydrosilylation. Les recherches futures pourraient explorer les possibilités mécanistiques, les différences cinétiques et la réactivité des complexes d'hydrures métalliques du groupe 2 avec le monoxyde de carbone pour l'homologation du CO
This research aimed to investigate the potential applications of Mg and Ca hydride complexes supported by ß-diketiminate and amidinate ligands for the reduction of CO2 molecules. The catalytic abilities of these complexes were explored in the context of hydroboration and hydrosilylation of CO2. In the first part of the study, we examined the reactivity of ß-diketiminato Mg and Ca hydrides with CO2. It was observed that the Mg hydride complex rapidly incorporated CO2, leading to the formation of various intermediates with different nuclearities. This involved the insertion of Mg—H bond into CO2, resulting in the generation of formate moieties. Under heat, hexameric formate complexes were formed through a "ligand flip" mechanism, releasing steric hindrances around the metal centers. For Ca hydride and CO2 reactions, in situ NMR analysis was mainly conducted. Additionally, a novel Mg amidinate dihydride complex was successfully synthesized and reacted with CO2 to yield a unique single product of dimeric formate Mg complex, in contrast to the ß-diketiminate scaffold, where several formate species were detected. The second part of the research focused on the catalytic hydroboration of CO2 using alkaline-earth hydride complexes. In particular, the Ca-based system demonstrated high efficiency in the production of the four-electron reduction of CO2 or BBA product. This was the first example of using Mg and Ca hydride compounds to catalyze the hydroboration of CO2, selectively producing the BBA product. The in situ generated BBA was further used as a methylene transfer reagent in condensation reactions with thiols, resulting in the formation of novel stable hemithioacetal [RS—CH2—OBR2] compounds under mild and neutral conditions. Activation of the hemithioacetal compounds was achieved under acidic conditions, leading to the formation of dithioacetals and hemithioaminals. The condensation of the second OBR2 fragment with secondary amines, which act as stronger nucleophiles, resulted in the generation of aryl methyl sulfides [RS—CH2—NR2]. In the final section, we investigated the tandem hydrosilylation of CO2 using various hydrosilanes in combination with [Ae]-based hydride complexes and Lewis acid B(C6F5)3 as catalysts. This research expanded on previous studies of Mg-mediated hydrosilylation of CO2 and introduced the first example of Ca-catalyzed CO2 hydrosilylation with hydrosilanes. The effectiveness of reducing CO2 to CH4 or bis(silyl)acetal [H2C(Ph3SiO)2] or BSA depended on the nature of the silanes and the steric hindrances around the substrate Si—H bond. The choice of [Ae] catalyst also significantly influenced the overall reaction rate. Furthermore, Eyring and Arrhenius analyses provided insight into the activation parameters for reducing CO2 by certain catalysts, revealing that this reaction is primarily governed by an entropic contribution. In summary, this research has demonstrated the reactivity of Mg and Ca hydride complexes for CO2 reduction and explored their applications in hydroboration and hydrosilylation reactions. Future investigations may explore mechanistic possibilities, kinetic differences, and the reactivity of group 2 metal hydride complexes with carbon monoxide for CO homologation

Résumé :

Asymmetric synthesis and catalysis is one of the leading research areas in chemistry society, for its versatility and efficiency in obtaining chiral molecules that found the vast majority in natural active compounds and synthetic drugs. Developing asymmetric catalytic methodology is at the frontier in both industrial and academic research laboratories. Enantioselective organocatalysis has emerged as a powerful synthetic tool that is complementary to metal-catalyzed transformations. The development of chiral phosphoric acid and metal phosphate as catalysts has been a breakthrough in recent years. Chiral phosphoric acids have been shown to be powerful catalysts in many organic transformations. Moreover, chiral metal phosphates, which formed by simply replacing the proton in phosphoric acid with metals, have introduced new catalytic activations and broaden the scope of phosphoric acids. This thesis details new highly enantioselective chiral phosphoric acid-catalyzed Pinacol rearrangement and robust alkaline phosphates catalytic system, which utilizes novel carbonyl activation.

The Pinacol rearrangement has long been known to be difficult to control in terms of regioselectivity and stereoselectivity. The initial studies found that indolyl-diol compounds can be treated with chiral phosphoric acids to afford the Pinacol rearrangement with high regio- and enantioselectivity. Over 16 chiral phosphoric acids were screened, and it was found an H8-BINOL-phosphoric acid variant with 1-naphthyl groups at 3 and 3' position was the excellent catalyst. This asymmetric transformation is tolerant toward variety of substituents both on the indole ring and migrating groups.

During the study, it was found that different ways to generate the catalyst had critical effect on this catalytic transformation. Only those phosphoric acids washed with HCl after column chromatography afforded the rearrangement products with high enantioselectivity. And those without treating with HCl were found contaminated by alkaline metals. These "contamination" catalysts were also found active with carbonyl activations.

A highly enantioselective catalytic hetero-Diels-Alder reaction of alpha-keto esters has been developed with chiral alkaline metal phosphates. A calcium 1-naphthyl-BINOL phosphate was found to be the optimum catalyst. A large range of alpha-keto esters as well as isatins can be applied in this alkaline phosphates catalytic system with high efficiency and selectivity. The structure of the catalyst is detailed for the first time by X-ray crystal structure analysis. A proposed Transition state model is provided based on the catalyst crystal structure and Raman spectroscopy analysis.

This methodology was further developed with an asymmetric Mukaiyama-Michael addition of beta,gamma-unsaturated alpha-keto ester. The best catalyst was found to be a magnesium chiral phosphate. And the transformation was found capable of tolerating a wide variety of beta,gamma-unsaturated alpha-keto esters.

Résumé :
This investigation addresses the understudied area of the research and development of hydrogen bonded metal-organic complexes featuring the alkaline earth metals magnesium and calcium. This work presents the crystal structures and thermal behaviour of a series of metal-organic and organic crystalline complexes synthesised from metal salts and pyridine carboxylic, dicarboxylic acid and chloranilic acid ligands, characterised primarily by X-ray diffraction. Chapter 1 introduces crystal engineering, intermolecular interactions, and functional crystalline materials, followed by a literature review addressing metal-organic frameworks (MOFs), hydrogen bonded metal-organic complexes, magnesium MOFs and alkaline earth metal complexes synthesised from pyridine carboxylic, dicarboxylic and tricarboxylic acid and chloranilic acid. Chapter 2 outlines the theory of the techniques used to analyse the synthesised materials, focusing on single crystal X-ray diffraction, followed by Chapter 3 which documents the sample preparation and the experimental details. Chapter 4 describes the crystal structures of fourteen coordination complexes synthesised from magnesium and calcium salts and the three isomers of pyridine carboxylic acid. This work was carried out in order to identify structural trends such as the most common coordination geometries of the metal centres, the ways in which the ligands coordinate and any recurring hydrogen bonding motifs. Chapter 5 discusses attempts to synthesise an alkaline earth metal analogue of a metal-containing ‘metalloligand’ of the formula M(C7H4NO4)2(H2O)2, in which the metal (M) is N,O-chelated by pyridine-2-carboxylate-4-carboxylic acid, and the subsequent combination of these materials with the diamines o-tolidine and m-xylylenediamine. This chapter also reports the structure of a magnesium coordination complex resulting from a hydrothermal reaction, and the subsequent transformation of this complex to a new crystal structure which contains the doubly deprotonated magnesium analogue of the originally targeted ‘metalloligand’. Chapter 6 describes the crystal structures of three complexes synthesised from pyridine carboxylic acids and chloranilic acid, and the complex resulting from the combination of one of these organic ‘supramolecular ligands’ with a copper salt. Finally, two new calcium-chloranilate coordination polymers are reported, one of which has an interesting anionic 3D structure.

Résumé :
Hydrogen as the most abundant element on Earth is viewed to be a promising energy carrier. For transmission, hydrogen stored as metal hydrides is a potent candidate for its advantages in safe and reliability and being able to offer high energy density compared to the conventional ways such as high pressure gas and liquefaction. Metal hydriding is basically an exothermic process. The heat released will cause an increase in temperature and raise the absorption equilibrium pressure as high as that of the supplied hydrogen gas, which may in turn stop the hydriding process. On the other hand, metal dehydriding is an endothermic process. A temperature decrease can retard desorption and even bring down the dissociation equilibrium pressure as low as the back pressure to stop dehydriding. Therefore, reducing thermal resistance of the storage vessels and enhancing heat transfer of the storage system have become a critical issue for the success of hydrogen storage using metal hydrides. This work models the metal hydriding/dehydriding process in order to assess the vessel design on heat transfer enhancement to improve the performance of hydrogen storage with metal hydrides. First of all, the thermal-fluid behavior of hydrogen storage was modeled including gas flow and energy equations. The vessel is considered to be equipped with an air pipe at the centre line with internal fins. Detailed theoretical models that describe force convection of the heat exchange pipe and natural convection at the lateral wall are constructed. Results from the simulation show that the addition of a concentric heat exchanger pipe with fins can enhance the reaction rates. The work demonstrates how computer aided engineering can be applied to evaluate the performance of hydrogen storage designs, and help reduce experimental efforts in developing the hydrogen storage systems.
