Full textHydrazines for propulsion have been identified by REACH regulation as Substances of Very High Concern (SVHC) and their use is therefore threatened. High Energy Density Materials (HEDM) represent a class of polynitrogen compounds with computed energetic performances breaking away from existing technologies. Besides solving toxicity issues thanks to their decomposition in molecular nitrogen, their use would highly simplify launcher’s technologies and decreases their cost. Two candidates have been proposed by the CNES and ArianeGroup to replace hydrazines: triaziridine (N3H3) and tetrazetidine (N4H4). The main goal of this thesis is to develop new methodologies for the synthesis of polynitrogen compounds and to investigate their reactivity to access to original structures such as triaziridine and tetrazetidine. Homologation of simple nitrogen-based compounds with azodicarboxylates enabled us to access new original superior polynitrogen molecules (N3, N4, N5, N6…). Structural evidences of these new polynitrogen backbones have been obtained by X-ray diffraction. Their reactivity by regioselective activation and by oxidation has been studied to access cyclic polynitrogen structures

Full textThe Ing-Manske reaction is a well-known variant of the Gabriel synthesis reaction which is used to synthetize primary amines under mild conditions. Yet, its mechanism has never been theoretically studied. Only few intermediates have been experimentally isolated or characterised. Its use with methyl pyrazepate showed an unexpected diastereoselective behavior that we have tried to clarify. The mechanism has been studied at the DFT-B3LYP level. Transition states and reaction intermediates have been calculated for various possible reaction pathways. Solvation effects, either microsolvatation or bulk effects (via PCM method), have been taken into account. On this basis some rationalization for the observed diastereoselectivity is proposed

Full textThis work aims at developing a new efficient synthetic route to N-functionalised hydrazine derivatives using N-aminophtalimide, N-acyl and N-alkyloxycarbonylaminophtalimides. The first part describes the synthesis of regioselective singly-labeled nitrogen 15 hydrazide, starting from N-aminophtalimide (15N). The direct application of this first study is the synthesis of two isotopic isomers of isoniazid (a front-line antituberculosis drug), which elucidate the activation of isoniazid by catalase-peroxydase from Mycobacterium tuberculosis. Moreover the reactivity of N-acyl and N-alkyloxycarbonylaminophtalimides which can be considered as hydrazines bearing three electron-withdrawing groups including two incorporated into the phtaloyl moiety, is developed in a second part. These compounds were used in phase transfert catalysis conditions and as acidic partners in the Mitsunobu reaction for the preparation of monoalkylhydrazines, monoalkylhydrazides and alkylcarbazates. In the third part , this current method was extented to include the preparation of protected chiral hydrazinoacid derivatives via the Mistunobu protocol. Finally the conformationel study and reactivity of N-aminophtalimide and its derivatives is reported

Full textThis work, conducted as part of a collaboration with the Safran-Heraklès group, aims at developing a new synthesis concept for the monomethylhydrazine (MMH), by process intensification using microreactor technology. The work was funded by the Rhône-Alpes region in the form of a doctoral fellowship TARGET 2008-2011. The first part of this research aims to study the stability of monochloramine solutions prepared in stoichiometric conditions. This synthesis was carried out continuously, for the first time ever, using microreactor technology. Optimal synthesis conditions as well as a set of security parameters have been established for a fast and secured transfer to industrial scale. The second part, also one of the main objectives of this work, is the extraction, under pressure, of all organic products (mostly MMH and monomethylamine) in the form of one condensed phase by demixing the crude reaction liquors. This phenomenon is related to the existence of a miscibility gap in the liquid ternary system H2O-MMA-NaOH. The optimization of the demixing step requires then the study of different solid-liquid-liquid phase diagrams involved. The last part deals with the chemical engineering aspect of the research. A kinetic modeling of the synthesis of MMH by the Raschig way was used in order to estimate the composition of the synthesis solution. These results and the application of phase diagrams allow the determination of optimal conditions for the isolation step and the establishment of process flow-sheets for the synthesis of MMH
