    Convenient synthesis and characterization of molecules containing multiple β-keto ester units
    摘要:
    Three compounds containing two beta-keto ester units and one containing three were obtained in good yields from sebacyl, terepthaloyl, isophthaloyl, and trimesoyl chlorides. In this one pot procedure the acid chlorides were first treated with ethyl acetoacetate and barium oxide and then with ethyl alcohol. The aliphatic ester exists mainly as keto ester with a very small amount of the enol tautomer. In the case of aromatic esters, all possible tautomers were found in considerable concentrations in deuterochloroform solution. Theoretical chemical shifts were estimated from GIAO/WP04/aug-cc-pVDZ/SCRF calculations, for a probable signal assignation for the corresponding tautomeric species. Our theoretical results are in agreement with experimental findings and account for negligible stability differences between the tautomers of each aromatic compound. (C) 2012 Elsevier Ltd.

  • Synthesis and Characterization of Phenylene-<i>bis</i>-pyrazolones and Nitrosation Derivatives
    作者:J. Belmar、L. Ortiz、J. Quezada、M. Parra、C. A. Jiménez
    DOI:10.1002/jhet.1843
    日期:2014.8
    Phenylene bis-pyrazolone derivatives were obtained by condensation of two aromatic β-diketo diesters with methyl-, 2-hydroxyethyl- and phenylhydrazines. The pyrazolone rings are connected to the central benzene ring by their C-3, leaving C-4 free for further derivatization. Thus, and despite their low solubility, these compounds were successfully nitrosated in good yield providing new chelating dioximes
    通过两个芳香族β-二酮二酯与甲基,2-羟乙基和苯肼的缩合反应制得苯二甲双吡唑酮衍生物。吡唑啉酮环通过其C-3连接至中心苯环,使C-4游离以进一步衍生化。因此,尽管它们的溶解度低,但仍成功地将它们以高收率成功地亚硝化,从而提供了新的螯合二肟。

    3-aminophenols with β-ketoesters in 19–96% yields. Among them, 7-(dimethylamino)-4-(pyridin-4-yl)-2H-chromen-2-one (3j) displayed a fluorescence maximum with a wavelength of 557 nm and a large Stokes shift of 166 nm in DMSO, and showed strong fluorescence in sub acid to alkaline environment. Besides, 3j exhibited excellent photo stability and stable fluorescence intensity in the presence of some metal cations

    In this study, we explore the untapped potential of ketocoumarins as photosensitizers for light driven hydrogen evolution. Through the synthesis of a library of novel ketocoumarins and optimization of the reaction conditions, we achieved remarkable turnover numbers nearing 4000 relative to the cobaloxime catalyst. Our spectroscopic and electrochemical studies revealed a reductive quenching mechanism
    在这项研究中,我们探索了酮香豆素作为光驱动析氢光敏剂的未开发潜力。通过合成一系列新型酮香豆素和优化反应条件,我们相对于钴肟催化剂实现了接近 4000 的显着转化率。我们的光谱和电化学研究揭示了析氢的还原猝灭机制。通过增加钴肟浓度,我们可以成功防止光敏剂的光降解,并且可以维持氢气生产长达 22 天。我们的工作表明,酮香豆素凭借其易于合成和可调节性,可以作为常用的重金属基光敏剂的有效且实用的替代品。
