  用于 Z-选择性烯烃复分解反应的氯化钼催化剂

  摘要：

  催化剂控制的立体选择性烯烃复分解过程的发展一直是化学领域的一项关键进展。在基于钼、钨和钌的配合物中掺入适当的配体导致了以前无法达到的反应性和选择性水平。在这里，我们表明，钼单芳氧基氯化物配合物通过与市售、廉价且通常惰性的 Z-1,1,1,4,4,4-六氟化合物的交叉复分解反应提供三氟甲基取代烯烃的高能 (Z) 异构体。 -2-丁烯。此外，用 Z-1,2-二氯乙烯和 1,2-二溴乙烯进行的低效和非立体选择性转化可以以显着提高的效率和 Z 选择性实现。使用这种钼单芳氧基氯化物复合物能够合成具有代表性的生物活性分子和医药相关化合物的三氟甲基类似物。在密度泛函理论计算的帮助下阐明了所观察到的活性和选择性水平的起源，这与先前提出的原则相矛盾。

• Transition‐Metal‐Free Radical Hydrotrifluoromethylation of Alkynes
  作者：Kiran Matcha、Andrey P. Antonchick

  日期：2019.1.23

  A combination of readily available and bench‐stable CF3SO2Na and tBuOOH was efficiently used for hydrotrifluoromethylation of alkynes. An excellent trans‐selectivity was demonstrated in the synthesis of alkenes. The developed mild reaction conditions allow the supression of the competing Meyer–Schuster‐type rearrangement.

  A visible-light-mediated hydrotrifluoromethylation of unactivated alkenes that uses the Umemoto reagent as the CF(3) source and MeOH as the reductant is disclosed. This effective transformation operates at room temperature in the presence of 5 mol % Ru(bpy)(3)Cl(2); the process is characterized by its operational simplicity and functional group tolerance.

• Metal-Free Photocatalytic Radical Trifluoromethylation Utilizing Methylene Blue and Visible Light Irradiation

  The use of organofluorine compounds, especially those with an incorporated trifluoromethyl moiety, has increased dramatically in both the pharmaceutical and agrochemical industry. It has therefore become imperative to develop a mild and efficient synthetic technique for the inclusion of trifluoromethyl groups. Herein, we report the first use of methylene blue as a photosensitizer for the catalytic radical trifluoro- and hydrotrifluoromethylation of electron-rich heterocycles as well as terminal alkenes and alkynes under visible light irradiation. These reactions proceed with moderate to good yields at low catalyst concentrations; short irradiation times; and most importantly, without the need for potentially toxic transition-metal catalysts. In this work, considerable emphasis was also placed on understanding the kinetics of the mechanistically key steps through the use of laser flash photolysis techniques to more efficiently optimize the reaction conditions.
