Texto completo da fonteSince the begining of space propulsion, launchers used low-power, polluting, and highly toxic technologies such as hydrazine and its derivatives. New, more powerful propellant mixtures have emerged. Cryogenic propellants like LOX/LH2, LOX/kerosene, or LOX/methane show significantly higher performance. Dense solid propellants also offer high thrust but cannot be reignited or throttled. This is the case with boosters (aluminum, ammonium perchlorate, and PBHT for Araine 5's EAP). The current goal is to find new propellants that possess the performance of cryogenics, the storability of hydrazines, and the density of solids. A class of new molecules offers all these advantages : High Energy Density Materials (HEDMs). These new high-value-added energetic molecules currently have theoretically calculated properties such as specific impulse and density, which are very interesting and in total technological breakthrought. They form gases with low molar weight at very high speeds through decomposition rather than combustion, aligning with the current trend of reducing costs, pollution, and toxicity, as well as the launcher’s size (Ariane Ultimate). This also allows for an increase the payload by using a smaller amount of propellant. The desired target of this thesis is triaziridine N3H3. This thesis work fits exactly within this dynamic and focuses on accessing a cyclic trinitrogenated molecules for space propulsion: triaziridine. To do this, the reactivity of azimines under photochemical conditions was studied. Initially, it was decided to build upon previous work conducted in the laboratory and to proceed with a complete optimization of the cyclization reaction to increase yields of triaziridine. Solvents, catalysts, and additives screenings were considered, and continuous flow transposition. Still aiming to obtain deprotectable triaziridines, a new one-pot method for azimine synthesis was developed, based on the electrophilic amination of functionalized hydrazine by an oxaziridine, leading to the corresponding triazane. This triazane will subsequently be oxidized by a hypervalent iodine derivative, allowing access to brand new aziminic skeletons. Finally, a theoretical DFT modeling study of the azimine photocyclization reaction was explored. This study shows the differents transition states that allow the cyclization of azimine into triaziridine. It also been initiated the development of a predictive model, which will guide the choice of cleavable substituents to introduce on the azimine to promote the photocyclization reaction
