  Heterobimetallic Ir–Sn catalysis: aza-Friedel–Crafts reaction of N-sulfonyl aldimines

  摘要：

  The heterobimetallic complex [Ir(COD)(SnCl3)Cl(mu-Cl)](2) catalyzes the aza-Friedel Crafts reaction of 1,3,5-trimethoxybenzene, as well as substituted indoles with N-sulfonyl aldimines leading to the formation of diarylamines and triarylmethanes in good yields. The symmetrical triarylmethanes were also obtained from diarylamines and suitable nucleophiles via simultaneous cleavage of sp(3) C-N bond and elimination of 1,3,5-trimethoxybenzene.

  A novel synthesis of bisheteroarylaryl methanes and triarylmethanes is described by the selective C–C bond cleavage of acetophenones in the presence of SeO2/lanthanide chlorides. The present strategy provides an in situ generation of aldehydes from acetophenones followed by a double Friedel–Crafts reaction of electron-rich arenes. Natural product 1,1,1-tris(3-indolyl)methane is synthesized in a single

  diheteroarylmethanes and 1,3-diheteroarylpropenes has been developed via Yb(III)-catalyzed sequential self-condensation of 2-furfuryl (or 2-thienyl or 3-indolyl) alcohols followed by intramolecular Friedel–Crafts type reaction and elimination of an aldehyde. This method offers a powerful entry and a potential alternative to the traditional synthesis of diheteroarylalkanes, which are precursors to the synthesis

  通过Yb（III）催化2-糠基（或2-噻吩基或3-吲哚基）醇的顺序自缩合反应，然后进行分子内Friedel-Crafts型反应，开发了一种有效的合成方法，用于二杂芳基甲烷和1,3-二杂芳基丙烯。消除醛。该方法为传统的二杂芳基烷烃的合成提供了有力的途径和潜在的替代方法，后者是几种有趣的杂芳基化合物的合成的前体，更重要的是生物燃料的合成。
• TEMPO/CuI synergetic catalyzed oxidative cross-coupling of indoles with benzylamines: Synthesis of bis(indolyl)phenylmethanes

  日期：2018.7.3

  TEMPO/CuI was found to be an effective catalyst for the cross-coupling of indoles with benzylic amines affording the corresponding bis(indolyl)phenylmethanes under air atmosphere at room temperature in good to excellent yields. The efficiency, easy workup, simplicity, and chemoselectivity of this protocol provide a green and low-cost procedure for the synthesis of these compounds.[GRAPHICS].
