    摘要:
    A mild and simple three-component procedure for the direct vicinal halotrifluoromethylation of styrenes and aliphatic alkenes has been developed in the presence of [Ru(bpy)(3)](PF6)(2) as a photosensitizer and Umemoto's reagent as the CF3 source. The multicomponent method offers the advantage of short reaction time, moderate to good yields, and mild reaction conditions.

  • Mechanistical insight into ‘electrophilic’ trifluoromethylation with S-(trifluoromethyl)dibenzothiophenium salts
    作者:Yohan Macé、Charlotte Pradet、Matthew Popkin、Jean-Claude Blazejewski、Emmanuel Magnier

    Trifluoromethyl sulfonium salts are widely used for the introduction of a trifluoromethyl group through reaction with a wide range of nucleophiles. Nevertheless, the reaction mechanism is far from obvious and has been the subject of various literature discussions. In this Letter, we show, through trapping experiments with a radical probe that, at least in the case of nucleophiles such as enol silyl
    三氟甲基sulf盐被广泛用于通过与多种亲核试剂反应引入三氟甲基。然而,反应机理远非显而易见,并已成为各种文献讨论的主题。在这封信中,我们通过自由基探针的捕获实验表明,至少在亲核试剂(例如烯醇甲硅烷基醚)的情况下,反应是通过SET进行的。
  • Ionic liquids as new media for electrophilic trifluoromethylation reactions
    作者:Bruce Pégot、Yohan Macé、Céline Urban、Patrick Diter、Jean-Claude Blazejewski、Emmanuel Magnier

    The electrophilic trifluoromethylation of aniline with a range of trifluoromethyl sulfonium salts has been studied in ionic liquids as solvent. The best ionic liquid for this reaction was identified after extensive scrutiny of the influence of the cation's nature (imidazolium or pyridinium salts), the effect of the alkyl side chain length of the cation, as well as that of the counter anion.

    已经在离子液体作为溶剂中研究了苯胺与一系列三氟甲基sulf盐的亲电子三氟甲基化。在广泛研究阳离子的性质(咪唑鎓或吡啶鎓盐),阳离子的烷基侧链长度以及抗衡阴离子的影响后,确定了用于该反应的最佳离子液体。循环实验表明,与在DMF中进行的常规反应相比,纯化程序得到了大大简化,并且溶剂可以重复使用五次而不会显着降低活性。
  • Photoredox-Induced Three-Component Azido- and Aminotrifluoromethylation of Alkenes
    作者:Guillaume Dagousset、Aude Carboni、Emmanuel Magnier、Géraldine Masson
    DOI:10.1021/ol5021477
    日期:2014.8.15
    We report herein a photoredox-catalyzed azidotrifluoromethylation of alkenes. Under the optimized conditions using [Ru(bpy)3(PF6)2] as the photocatalyst and Umemoto's reagent as the CF3 source, a wide range of substituted styrenes as well as various activated and nonactivated alkenes can readily be difunctionalized, affording β-trifluoromethylated azides or amines in good yields.

    tricyclic dibenzothiophenium salts. New compounds were tested, in a standard reaction with aniline, for their trifluoromethylating power and revealed equivalent or improved reactivity relative to that of existing reagents. Furthermore, contrary to common knowledge, the presence of electron-donating methyl groups gave reagents with very high activity.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany
