  • Nucleophilic introduction of fluorinated alkyl groups into aldehydes and ketones using the corresponding alkyl halide with samarium(II) iodide
    作者:Masato Yoshida、Daiki Suzuki、Masahiko Iyoda
    DOI:10.1039/a606048j
    日期:——
    Fluorinated alkyl groups such as PhCF2, C6F13, CF3CCl2 and CF2CO2Et are nucleophilically introduced into an aldehyde or ketone using fluorinated alkyl halides with SmI2; the reaction proceeds effectively at room temperature to give the corresponding alcohol. Furthermore, the synthesis of PhCF2SiMe3, C6F13SiMe3 and C6F13SiMe2Pri is achieved by reaction of the halide with SmI2 in the presence of the silyl chloride; the resultant fluoroalkylated silyl compounds are used as reagents for nucleophilic fluoroalkylation. 2-Chloro-3,3,3-trifluoropropene derivatives are also prepared selectively by the reaction of CF3CCl3 with an excess of SmI2 in the presence of an aldehyde and PriOH.
    氟代烷基如PhCF2、C6F13、CF3CCl2和CF2CO2Et可以通过氟代烷基卤化物与SmI2在室温下有效反应,亲核引入醛或酮中,形成相应的醇。此外,通过卤化物与SmI2在硅氯化物存在下的反应,实现了PhCF2SiMe3、C6F13SiMe3和C6F13SiMe2Pri的合成;由此得到的氟代烷基硅化合物作为亲核氟代烷基化的试剂。2-氯-3,3,3-三氟丙烯衍生物也通过CF3CCl3与过量的SmI2在醛和PriOH存在下的反应选择性制备。

    N-Heterocyclic carbenes (NHCs) have been employed as highly efficient organocatalysts for fluorinated silyl-Reformatsky reaction of carbonyl compounds. In the presence of 5–10 mol % NHC A, various aldehydes and 2,2,2–trifluoroacetophenone reacted with difluoro (trimethylsilyl) acetate to produce β–hydroxy gem–difluoro esters in 20–96% yields.

  • Nickel-Catalyzed Reductive Cross-Coupling of (Hetero)Aryl Iodides with Fluorinated Secondary Alkyl Bromides

    DOI:10.1021/acs.orglett.5b02716
    日期:2015.11.20
    A mild and efficient nickel-catalyzed reductive cross-coupling between fluorinated secondary alkyl bromides and (hetero)aryl iodides is described. The use of FeBr2 as an additive successfully overcomes the hydrodebromination and β-fluorine elimination of fluorinated substrates and allows the efficient synthesis of a wide range of trifluoromethyl and difluoroalkyl containing aliphatic compounds with
    描述了在氟化仲烷基溴化物和(杂)芳基碘化物之间温和有效的镍催化的还原交叉偶联。使用FeBr 2作为添加剂可成功克服氟化底物的加氢脱溴作用和β-氟消除作用,并允许有效合成范围广泛的含三氟甲基和二氟烷基的带有氟烷基取代的叔碳中心的脂肪族化合物。该方案的显着特点是无需制备对水分敏感的有机金属试剂,合成和操作简单,并且即使对于含活性质子的底物也具有出色的官能团相容性。
  • A convenient method for the preparation of α,α-difloro-β-ketoesters and α,α-difluoroamides from terpenic and perfumery aldehydes
    作者:Shoji Watanabe、Tsutomu Fujita、Masami Sakamoto、Hiromichi Takeda、Tomoya Kitazume、Takashi Yamazaki

    日期:1997.4
    Reformatsky reactions with ethyl bromodifluoroacetate gave α,α-difluoro-β-hydroxyesters in good yield from the corresponding terpenic and perfumery aldehydes. α,α-Difluoro-β-ketoesters were prepared by Swern oxidation of the α,α-difluoro-β-hydroxyesters. The reaction of hydroxyesters with amines in the presence of lipase MY, lipase PS or Novozym 435 gave α,α-difluoroamides.
