  Iridium-Catalyzed Cycloaddition of Azides and 1-Bromoalkynes at Room Temperature

  摘要：

  Iridium dimer complexes were found to catalyze the [3 + 2] cycloaddition reaction of azides with bromoalkynes, yielding 1,5-disubstituted 4-bromo-1,2,3-triazoles in reasonable to excellent yields under mild conditions. The reaction offers a direct route to new 1,4,5-trisubstituted triazoles.

• Palladium-Catalyzed Direct Arylations of 1,2,3-Triazoles with Aryl Chlorides using Conventional Heating
  作者：Lutz Ackermann、Rubén Vicente、Robert Born

  DOI：10.1002/adsc.200800016

  日期：2008.3.25

  Generally applicable, palladium-catalyzed direct arylations of 1,2,3-triazoles with aryl chlorides were accomplished through conventional heating at reaction temperatures of 105–120 °C. Thereby, intra- and intermolecular CH bond functionalizations were achieved with a variety of differently substituted chlorides as electrophiles, bearing numerous valuable functional groups.

  通常适用的是，通过在105-120°C的反应温度下进行常规加热来实现1,2,3-三唑与芳基氯化物的钯催化直接芳基化。因此，用各种不同取代的氯化物作为亲电子体，实现了分子内和分子间的CH键官能化，并带有许多有价值的官能团。

  Cu(I) and nanoparticles of Pd supported on ethylenediamine‐functionalized cellulose as a novel bio‐supported catalyst was synthesized and characterized. The synthesized catalyst was found to be a highly efficient heterogeneous catalyst for the synthesis of 1,4,5‐trisubstituted 1,2,3‐triazoles through a sustainable 1,3‐dipolar cycloaddition/direct arylation sequence. The catalyst could be easily recovered

• Bench-Stable 5-Stannyl Triazoles by a Copper(I)-Catalyzed Interrupted Click Reaction: Bridge to Trifluoromethyltriazoles and Trifluoromethylthiotriazoles

  Metalated triazoles are the key reactive intermediate of the current click reaction (CuAAC). Bench-stable 5-stannyl triazoles are obtained by a copper-catalyzed interrupted click reaction of easily available terminal alkynes. Subsequent palladium-catalyzed cross-coupling reactions, electrophilic trifluoromethylthiolation and trifluoromethylation, generate diverse 1,4,5-trisubstituted triazoles efficiently

  金属化的三唑是电流点击反应（CuAAC）的关键反应中间体。稳定的5-锡烷基三唑是通过铜催化的易获得的末端炔烃的间断点击反应而获得的。随后的钯催化的交叉偶联反应，亲电子的三氟甲基硫醇化和三氟甲基化，可以有效地生成各种1,4,5-三取代的三唑，而传统的点击反应是无法完成的。

• Cu/Pd-Catalyzed, Three-Component Click Reaction of Azide, Alkyne, and Aryl Halide: One-Pot Strategy toward Trisubstituted Triazoles

  A Cu/Pd-catalyzed, three-component click reaction of azide, alkyne, and aryl halide has been developed. By using this Cu/Pd transmetalation relay catalysis, a variety of 1,4,5-trisubstituted 1,2,3-triazoles were quickly assembled in one step in high yields with complete regioselectivity, just like assembling Lego bricks. Notably, different from the well-established CuAAC click reactions only working on terminal alkynes, this reaction offers an alternative solution for the problem of the click reaction of internal alkynes.
