  • Triflylation of 1,4-Benzoquinones with sodium trifluoromethanesulfinate
    作者:Sheng-Li Yue、Min Jiang、Hui Li、Jin-Tao Liu
    DOI:10.1016/j.jfluchem.2019.109410
    日期:2019.12
    The iodine-promoted triflylation of 1,4-benzoquinones with cheap and easily available sodium trifluoromethanesulfinate is achieved under mild conditions. A series of aryl triflones were obtained in moderate to good yields. The method could also be extended to triflylation of 1,4-benzoquinone monoamines and perfluoroalkanesulfonylation with sodium perfluoroalkanesulfinates.
    在温和的条件下,用便宜且容易获得的三氟甲烷亚磺酸钠实现了碘促进的1,4-苯醌的三氟甲基化。以中等至良好的产率获得了一系列芳基三氟甲磺酸。该方法还可以扩展到1,4-苯醌单胺的三氟甲基化和全氟烷磺酸亚磺酸钠的全氟烷磺酰基化。
  • Ionic Liquids-Promoted Addition of Arylsulfinic Acids to <i>p</i>-Quinones: A Green Synthesis of Diaryl Sulfones
    作者:J. Yadav、B. Reddy、T. Swamy、N. Ramireddy
    DOI:10.1055/s-2004-829145
    日期:——
    Arylsulfinic acids undergo smooth conjugate addition to p-quinones in air- and moisture-stable second generation room temperature ionic liquid [bmim]BF 4 under mild conditions to produce the corresponding arylsulfonylhydroquinones in excellent yields with high selectivity. In this reaction, ionic liquid plays the dual role as the solvent and the catalyst. The quinones show enhanced reactivity in ionic
    芳基亚磺酸在空气和水分稳定的第二代室温离子液体 [bmim]BF 4 中在温和条件下与对醌进行平滑共轭加成,以优异的收率和高选择性生成相应的芳基磺酰基氢醌。在这个反应中,离子液体起到了溶剂和催化剂的双重作用。醌类在离子液体中表现出增强的反应性,从而缩短了反应时间并显着提高了产率。离子液体的存在有助于避免使用酸或碱催化剂进行这种转化。回收的离子液体可重复使用四到五次,活性一致。
  • Antioxidant for yellow grease
