Abstract:
Abstract. The kinetics of the gas phase reactions of hydroxyl radicals with two unsaturated ketoethers (UKEs) at (298±3) K and 1 atm of synthetic air have been studied for the first time using the relative-rate technique in an environmental reaction chamber by in situ Fourier-transform infrared spectroscopy (FTIR). The rate coefficients obtained using propene and isobutene as reference compounds were (in units of 10−10 cm3 molecule−1 s−1) as follows: kTMBO (OH + (E)-4-methoxy-3-buten-2-one) = (1.41±0.11) and kMMPO (OH + (1E)-1-methoxy-2-methyl-1-penten-3-one) = (3.34±0.43). In addition, quantification of the main oxidation products in the presence of NOx has been performed, and degradation mechanisms for these reactions were developed. Methyl formate, methyl glyoxal, peroxyacetyl nitrate (PAN) and peroxypropionyl nitrate (PPN) were identified as main reaction products and quantified for both reactions. The results of the present study provide new insights regarding the contribution of these multifunctional volatile organic compounds (VOCs) in the generation of secondary organic aerosols (SOAs) and long-lived nitrogen containing compounds in the atmosphere. Atmospheric lifetimes and implications are discussed in light of the obtained results.

Abstract:
L'action d'aldéhydes aromatiques sur des pivalolaminopyridines ortho lithiées a donné des alcools secondaires qui ont été oxydés en cétones. Ceci permettant une synthèse en 4 étapes des amino-2 pyridyl-3, amino-3 pyridyl-4 et amino-4 pyridyl-3 arylméthanones. De la même façon, la fluoro-4 lithio-3 pyridine conduit à l'amino-4 pyridyl-3 phénylméthanone. Pour montrer l'intérêt de la méthode, des pyridopyrimidinones et des benzonaphtyridines ont été synthétisées. Par ailleurs, la fluoro-2 pyridine métallée, réagit avec l'iode pour donner des iodo-3 pyridines diversement substituées en 2. Une synthèse en 2 étapes des ortho iodo aminopyridines a été développée à partir des trois monoaminopyridines. La substitution de l'iode par des énolates dans les conditions de la SNR1 conduit après cyclisation acide aux aza-5, -6 et -7 indoles substitués en 2. Enfin, des aza-5 indoles disubstitués en -2, -3 ont été obtenus par action d'alphaméthoxycétones sur la lithio-3 pivalamido-4 pyridine et cyclisation acide

Abstract:
Des derives phosphonoindoliques sont prepares par cyclisation d'arylhydrazones d'oxoalkylphosphonates selon fisher et par cyclodeshydratation d'arylamino-1 et arylamino-3 oxo-2 propylphosphonates selon bischler. Des indolyl-2 et indolyl-3 phosphonates, des indolylmethyl-2 et des indolylmethyl-3 phosphonates diversement substitues et leurs acides phosphoniques correspondants sont decrits. Toutes structures sont analysees par rmn **(1)h, **(31)p et 1**(3)c. L'analogue phosphore de l'intermediaire a aussi ete prepare. L'extention de la reaction de bischler aux aryloxycetones permet d'atteindre des benzofuryl-2 phosphonate et de benzofurylmethyl-3 phosphonates. Deux nouveaux reactifs sont utilises pour acceder aux arylaminocetones et aux aryloxycetones : les chloro-1 et chloro-3 methoxycarbonylhydrazono-2 propyl-phosphonates de diethyle, composes qui, traites en milieu basique, donnent des azoenes qui additionnent les anilines et les phenols. Ces azoenes additionnent aussi les carbanions, notamment les carbanions derives de cetones pour conduire, apres hydrolyse soit a des derives du pyrrole, soit a des dioxy-2, -5-alkylphosphonates precurseurs de cyclopentenones selon wittig-horner
