    摘要:
    Perfluoroketene dithioacetals were prepared in high yields from perfluoroaldehyde hydrates via their thioacetalization (TiCl4/CH2Cl2) followed by basic phase transfer catalyzed HF elimination. Acidic hydrolysis (CF3CO2H, H2O) and then transesterification (EtOH, Ti(OiPr)4) yielded S-alkyl 2-hydroperfluoro thioesters and ethyl 2-hydroperfluoro esters, respectively.

  • Synthesis, metallation and nucleophilic reactivity of 2,6-bis(trialkylsilyl)-<i>4H</i>-thiopyrans

    -4H-thiopyran. Its lithium salt exhibited also interesting properties: Peterson olefination products were formed under reaction with aldehyde, and a stable thiabenzene was effectively obtained with n-hexylbromide. The role of the silyl substituents was decisive to explain the particular aspects of the reactivity of these silyl substituted thiopyrans. GRAPHICAL ABSTRACT
    我们在本文中报告了 (i) 通过 1,5-双(酰基硅烷) 硫化-环化合成 2,6-双(三烷基甲硅烷基)-4H-噻喃和 (ii) 这些噻喃的锂化以及它们的锂盐与各种亲电试剂。大多数反应导致 4 位和 2 位碳的烷基化,前者通常更具区域选择性。在正己基溴的情况下发生在硫原子上的部分反应。有效且完全区域选择性的三甲基甲硅烷基化产生了 2,4,6-三(三烷基甲硅烷基)-4H-噻喃。它的锂盐也表现出有趣的特性:与醛反应形成彼得森烯化产物,与正己基溴有效地获得稳定的噻苯。甲硅烷基取代基的作用对于解释这些甲硅烷基取代的噻喃的反应性的特定方面是决定性的。
  • Nucleophilic chain substitution on perfluoroketene dithioacetals by ethyl 2-trimethysilyl acetate. Application to the synthesis of 2-trifluoromethyl succinic acid derivatives

    A highly efficient substitution of the vinyl fluoride of perfluoroketene dithioacetals was achieved using trimethylsilylacetate to give 2-perfluoroalkyl succinic acid derivatives and 2-trifluoromethyl succinimides. This chain process was initiated by a catalytic amount of fluoride salt, whereas reaction failed with the corresponding lithium enolate.

    The present paper describes the Diels–Alder reactions of perfluoroketene dithioacetals with electron-rich 1,3-dienes (2,3-dimethylbuta-1,3-diene, isoprene, penta-1,3-diene) followed by spontaneous HF and thiol elimination, leading to polysubstituted aromatic sulfides in moderate to good yields. Reactions seem to be dependent on the substitution patterns of perfluoroketene dithioacetals; the best results
    本文描述了全氟乙烯二硫缩醛与富电子的1,3-二烯(2,3-二甲基丁-1,3-二烯,异戊二烯,五-1,3-二烯)的Diels-Alder反应,然后是自发的HF和硫醇消除,导致多取代的芳族硫化物以中等至良好的收率。反应似乎取决于全氟乙烯二硫缩醛的取代方式。从三氟甲基或五氟乙基和乙基硫烷基衍生物获得最佳结果。在DFT级进行的理论计算与实验结果非常吻合,表明整个过程由环加成步骤控制。
  • Fluoride-induced coupling of perfluoroketene dithioacetals with silyl alkynes: A way towards new polyfunctionalized trifluoromethyl building blocks

    activation, the vinyl fluorine of perfluoroketene dithioacetal may be substituted by silylated nucleophiles. Using silyl alkynes, a formal transition metal free sila-Sonogashira cross-coupling reaction occurred. The resulting enynes were hydrolyzed giving new polyfunctional trifluoromethyl building blocks.
