Full textThis thesis aims to study and to apply reactions of alcohols under hydrothermal conditions.Studies on 1-phenyl-ethanediol show an aldolisation, followed by an intramolecular Friedel-Crafts type reaction and an aromatisation. Finally, it ends up by as 1-phenyl-naphthalene.Ethylene glycol reacts on itself with a strong dependence on the temperature and the solvent. The conversion of 1,2-propanediol showed similar dependences and obtained even the aromatic compound mesitylene and especially the amount of products proves dependence on the temperature and the duration of the reaction. The main compounds can be used as solvents, as biofuel and for syntheses, whereas the byproducts might be biocarburants after hydrogenation.The Friedel-Crafts type reaction is transferred to an intermolecular one. Naphthalene and phenol are studied in more detail. 0.05mol/L HCl are enough in order to benzylate an aromatic compound at 180°C. HCl can be replaced by acetic acid or formic acid, but even concentrations of 1.0mol/L do not achieve results as good as 0.05mol/L HCl. The recycling of the aqueous phase of these reactions is advantageous. Additionally, benzyl alcohol alkylates benzyl alcohol and thus it can polymerize. Higher temperatures lead to longer polymers. This polymerization can be used in the domain of nuclear fuel recycling in order to separate platinum group metals out of a model solution

Full textSupported reactifs present some advantages in organic synthesis : simplification of experimental procedures, use of common solvents, regeneration and reuse of support. The first goal of this work was the exploration of some new reactions using exchange resins. For classical functionel transformations or for sulfides and selenides preparations. Thus, we have realized : the hydrogenolysis of primary halides by a borohydrure resin. In the second part of this work, we extend the study of oxydatite properties of chlorite and hypochlorite salts. Thus we have found chemoselective conditions for the oxydation sulfide, sulfoxide using factorial design. We propose an previsionnal method for chemical shift determination in NMR 13C of sulfide, sulfone, sulfoxyde and selenide

Full textThree topics were studied during this Ph. D. Thesis. We first reported a new manganese-catalyzed oxidative cross-coupling reaction of alkynyl, alkenyl and aryl magnesium halides with oxygen as an oxidant. The reaction is chemo- and stereoselective, and allows obtaining a vast array of conjugated unsaturated products. We also developed a copper-catalyzed cross-coupling reaction between alkynyl halides and alkyl or aryl Grignard reagents. The reaction is chemoselective, and allows obtaining a wide range of simple or functionalized alkynes in excellent yields. To the best of our knowledge, this is the first report concerning the use of secondary and tertiary alkyl, as well as aryl Grignard reagents for this type of coupling. On the other hand, we disclosed simple procedures for the copper-catalyzed alkylation of alkyl and aryl magnesium halides with alkyl bromides. We also discovered that the copper-catalyzed substitution of alkyl halides can be performed using alkyl, aryl and vinyl lithium compounds. It should be noted that, to the best of our knowledge, organolithium compounds have never been used to perform alkylation reactions in the presence of a catalytic amount of copper. Finally, we disclosed a new method for the preparation of "salt free" diorganozinc compounds in two steps. This procedure allows a very simple access to various dialkyl and diarylzinc compounds in good yields

Full textOrganofluorine chemistry as a whole can be divided into two main topics. While the first concerns the synthesis of specific fluorinated moieties, either through the creation of C-F bonds or by the elaboration of an already fluorinated motif, the second one deals with the cleavage of the C-F bond, the strongest single bond carbon can make with any other element. The current study of the reactivity of allylic and propargylic mono- and difluorides with certain nucleophiles, separated in three projects for which catalysis ended being at the very core, had us delve into those two areas of organofluorine chemistry. The first project involves the preparation of monofluoroalkenes. Notwithstanding the abundant literature on the subject, a general and versatile route to monofluoroalkenes is still sought after. Our initial approach revolved around the nucleophilic substitution of 3,3-difluoropropenes. However, our attempts at platinum catalysis and nickel catalysis did not meet expectations. The breakthrough came from resorting to 3-chloro-3-fluoropropenes as no transition metal was now necessary in most cases for the allylic substitution to occur, and this with an unmatched scope of nucleophiles. The success of the transformation is only attributable to the difference in leaving group ability of a fluorine atom and a chlorine atom in geminal relationship. The second project focusses on C-F bond activation as applied to propargylic monofluorides. While strong conditions are commonplace for C-F bond activation, our group approaches this problem through hydrogen bonding, a weak interaction. This has led us to develop the Friedel-Crafts reaction of propargylic monofluorides. Finally, the last project concerns the hydrofunctionalization of propargylic gem-difluorides under gold catalysis. To this date, both the hydration and hydroalkoxylation reactions were explored. The transformation displays a perfect regioselectivity for nucleophilic attack onto the carbon of the alkyne distal to the fluorinated unit. DFT calculations point towards the electronic bias brought about by the fluorine atoms as being at the origin of this unusual selectivity.

Full textFuniculosin and Cladobotryal have both a good antifungal activity. For this reason, it was of interest to elaborate analogues of these compounds in order to evaluate their biological activities. To this end, 4-alkoxy-1-alkyl-2-pyridones halogenated at positions 3 and/or 5 have been synthesized. These compounds were engaged in regio- or chemoselective palladium-catalyzed coupling reactions to access, on the one hand, differentially 3,5-diarylated pyridones as Funiculisin analogues and, on the other hand, a series of alkynylpyridones. The latter were further elaborated to reach a range of furo[3,2-c]pyridin-4-ones and furo[3,2-c]pyridin-6-ones disubstituted at positions 2 and 7 via a new radical deprotection/cyclisation reaction, as well as various furo[2,3-b]pyridin-4-ones trisubstituted at positions 2, 3 and 5, as Cladobotryal analogues, through iodocyclisation followed by various coupling reactions at position 3
