Abstract:
In the title compound, C11H18N2 2+·2Br−, whose cation represents the product of racemization of an L-proline derivative under basic conditions, the pyrrolidinium ring has a distorted envelope conformation with the N atom deviating by 0.533 (6) Å from the mean plane of the remaining four atoms of the ring. The methylene C atom which connects the pyrrolidinium ring and the 2-methylpyridine group is displaced from the plane of the four pyrrolidinium C atoms by 0.625 (8) Å in the same direction as the N atom. The cation and anions are linked by N—H...Br hydrogen bonds.

Abstract:
Pyrrolidinium-based (Pyr) ionic liquids are a very wide family of molecular species. Pyrrolidinium cations are electrochemically stable in a large potential interval and their molecular size hinders their transport properties. The corresponding ionic liquids with trifluoromethyl sulphonyl imide anions are excellent solvents for lithium/sodium salts and have been demonstrated as electrolytes in aprotic batteries with enhanced safety standards. In this study, the analysis of the physicochemical properties of a homologous series of pyrrolidinium-based ionic liquids with general formula Pyr1,xTFSI (x = 1–8) have been tackled by first principles calculations based on the density functional theory. The molecular structures of isolated ions and ion pairs have been predicted by electronic structure calculations at B3LYP level of theory in vacuum or in simulated solvents. Thermodynamic properties have been calculated to evaluate the ion pairs dissociation and oxidation/reduction stability. This is the first systematic computational analysis of this series of molecules with a specific focus on the impact of the length of the alkyl chain on the pyrrolidinium cation on the overall physicochemical properties of the ion pairs.

Abstract:
Ce memoire presente la synthese de polyheterocycles en serie isoindolique et pyrrolidinique. Dans une premiere partie, nous avons etudie l'elaboration de quinoleinones, benzazepinones et benzothiazocinones. L'etape de cyclisation consiste en une acylation de friedel & crafts d'acides acetiques ou thioglycoliques fonctionnalises. Ces precurseurs ont ete prepares par formation d'imides puis reduction en hydroxylactames suivie soit d'une thionation soit d'une reaction de wittig. Plusieurs des polyheterocycles obtenus ont ete synthetises a plus grande echelle pour etudier leur reactivite. Des reactions de schmidt, des transpositions de baeyer-villiger. . . Ont ainsi ete realisees avec succes. L'elaboration de composes possedant un motif 1,4-oxa(thia ou dia)azepine a ete mise en oeuvre dans une seconde partie. Les precurseurs hydroxylactames ont genere en milieu acide des ions n-acyliminiums qui ont conduit aux structures azepiniques selon une -cyclisation. Lorsque l'hydroxylactame possede un atome d'azote en tant que nucleophile interne, une structure imidazolique peut se former au moyen d'une quantite catalytique d'apts selon une -azaamidoalkylation intramoleculaire. Des polycycles imidazoliques analogues ont egalement ete formes par condensation de diamines sur des cetoacides. Dans une troisieme partie, nous avons etudie la reactivite d'une enamidone issue d'un rearrangement de meyer-schuster. Un couplage radicalaire n'a pas conduit a l'isoquinoleine attendue mais a un produit de reduction de la liaison c=c. D'autre part, un couplage palladie a fourni le produit desire avec un rendement modere. La plupart des composes synthetises ont ete soumis a une evaluation biologique. Parmi eux, sept composes ont une activite biologique moderee ou elevee en protection des plantes, en bacteriologie- mycologie ou en cancerologie.

Abstract:
Ce travail a consiste en l'etude experimentale de la diasteroselectivite de la reaction de michael des imines, a son extension a de nouveaux types d'olefines electrophiles substituees et a des applications synthetiques de composes biologiquement actifs. Dans un premier temps, nous avons confirme experimentalement le modele theorique de l'approche compacte de type chaise de l'enamine secondaire et de l'electrophile substitue, en determinant les relations stereochimiques des substituants dans les adduits obtenus. A partir de l'adduit obtenu par reaction d'alkylation d'une imine fonctionnalisee avec l'anhydride maleique, une nouvelle reaction d'aromatisation a permis d'obtenir un indole intermediaire cle pour la realisation de la synthese totale de la serotonine et de ses derives. Dans l'objectif d'utiliser un nouvel electrophile plus reactif, nous avons effectue la reaction d'alkylation des imines avec les nitro-olefines. Dans le cas des imines -substituees, contrairement au cas des olefines electrophiles habituelles, les adduits majoritaires sont issus de l'alkylation sur l'atome de carbone le moins substitue et la reaction est suivie immediatement par une cyclisation-aromatisation fournissant ainsi les composes tetrahydroindoliques correspondants. Avec les nitro-olefines, nous avons ensuite effectue la reaction de michael avec generalement une tres haute enantioselectivite en utilisant des enaminoesters chiraux. En effet, la liaison hydrogene des adduits obtenus permet de stabiliser ces derniers, evitant ainsi l'aromatisation qui detruirait le centre asymetrique tertiaire forme. La reduction en amine de la fonction nitro de ces adduits, suivie de cyclisation avec elimination de la copule chirale, a fourni enantioselectivement des pyrrolidines 2,3,4-tri-substituees apres une reduction stereo-controlee de la double liaison formee. Cette partie de ce travail nous a permis d'effectuer les syntheses asymetriques formelles de deux composes d'interet biologique.

Abstract:
Ionic liquids are widely considered as potential electrolytes for lithium batteries due to their tunable electrochemical properties and extremely low vapor pressure, which makes them highly non-inflammable. However, the solubility of oxygen in ionic liquid based electrolytes is an important parameter that determines the performance of batteries. In the present study, we have employed molecular dynamics simulations to calculate the Henry’s constant and corresponding solubility values of atmospheric oxygen in N-methyl-N-propyl pyrrolidinium bis(trifluoromethanesulfonyl) imide (mppy+TFSI−) ionic liquids. After qualitatively validating the results at 323 K, we calculated the solubility of oxygen in mppy+TFSI−, as the ratio of the partial pressure of oxygen gas in the atmosphere and the Henry’s constant, at a range of temperatures that occur in realistic battery electrolytes. The solubility of oxygen increases with increasing temperature. Comparison of these solubility values with those of commonly used organic electrolytes provides valuable information regarding the feasibility of using ionic liquid electrolytes in lithium-air batteries.

Abstract:
Based on ever-growing societal demand for stable energy supply, recent times have witnessed an increasing emphasis on developing energy storage devices such as batteries with improved specific energy and specific power. Among the myriad energy-storage technologies, rechargeable lithium ion batteries are widely used as energy sources for a range of portable electronic devices because of their relatively high specific energy storage capabilities [1]. However, the highest energy storage capacity achieved by a state-of-the-art lithium ion battery is too low to meet current demands in larger applications such as in the automotive industry [1]. The limitation is due, in part, to the limited ionic conductivity of currently used organic electrolytes coupled with their volatility, electrochemical instability and flammability, which raises safety concerns. The development of new generation of lithium ion batteries with significantly improved energy storage would require the selection of novel electrolyte materials with improved performance without compromising on safety standards. In recent years, there has been growing interest in the development of room temperature ionic liquids because they have extremely low vapor pressure, are stable at high temperatures, are highly resistant to oxidation and reduction, possess high ionic conductivity and have tunable electrochemical properties. However, the ionic conductivity of ionic liquids doped with lithium salt is extremely sensitive to the molecular structure of the ions as well as the extent of coordination between neighboring ionic species. In an effort to understand how atomistic interactions determine transport properties of ionic liquids, in the current study, we simulated lithium salt doped pyrrolidinium based ionic liquids using fundamental atomistic simulations. Properties such as density and self-diffusion coefficients were determined from molecular dynamics simulations and compared to experimental data to validate our model. Our simulations indicate that the mobility of lithium ions is limited due to association with multiple salt anions.
