    their increased photocatalytic activity toward trifluoromethylation with various substrates, such as (hetero)arenes and vinylic amides/acids, via addition, cyclization, and decarboxylation under visible light. The economic significance of this strategy is also highlighted through the scalable synthesis of biologically active molecules followed by catalyst reuse. Moreover, these catalysts are relatively

  • Graphitic Carbon Nitride Polymer as a Recyclable Photoredox Catalyst for Fluoroalkylation of Arenes
    作者:Moritz Baar、Siegfried Blechert
    DOI:10.1002/chem.201405505
    日期:2015.1.7
    Heterogeneous catalysis for trifluoromethylations and perfluoroalkylations has been performed. Through the usage of cheap, metal‐free and recyclable mesoporous graphitic carbon nitride (mpg‐CN) it was possible to fluoroalkylate various arenes by the reductive activation of sulfonyl chlorides with visible light. Thus, we were able to demonstrate the robustness and versatility of mpg‐CN as a photoredox

    Iron photocatalysis enables repurposing inexpensive trifluoroacetates as reagents for the C(sp2)−H trifluoromethylation. Thanks to the complementary inner-sphere electron-transfer pathway, photodecarboxylation occurs under mild conditions and can be applied to complex molecules, including natural products and pharmaceuticals.

  • Metal-Free Photocatalytic Radical Trifluoromethylation Utilizing Methylene Blue and Visible Light Irradiation
    作者:Spencer P. Pitre、Christopher D. McTiernan、Hossein Ismaili、Juan C. Scaiano
    DOI:10.1021/cs5005823
    日期:2014.8.1
    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.
  • Trifluoromethylation of heterocycles via visible light photoredox catalysis
    作者:Naeem Iqbal、Sungkyu Choi、Euna Ko、Eun Jin Cho
    DOI:10.1016/j.tetlet.2012.02.032
    日期:2012.4
    A method has been developed for the visible light-induced trifluoromethylation of heterocyclic compounds. A variety of electron-rich heterocycles were transformed into trifluoromethylated products by using CF3I as the trifluoromethyl radical source and Ru(bpy)(3)Cl-2 as the photocatalyst under mild reaction conditions. This operationally simple and eco-friendly process can introduce trifluoromethyl groups without prefunctionalization. (C) 2012 Elsevier Ltd. All rights reserved.
