  palladium-catalyzed coupling of aryl triflates with pyrazole derivatives is described. Using tBuBrettPhos as a ligand, the palladium-catalyzed C–N coupling of a variety of aryl triflates including ortho-substituted ones with pyrazole derivatives proceeded efficiently to give N-arylpyrazole products in high yields. 3-Trimethylsilylpyrazole was found to be an excellent pyrazole substrate for the coupling, and the corresponding

  描述了通过钯催化的芳基三氟甲磺酸酯与吡唑衍生物的偶合来合成N-芳基吡唑的方法。使用t BuBrettPhos作为配体，钯催化的各种芳基三氟甲磺酸酯（包括邻位取代的芳基三氟甲磺酸酯）与吡唑衍生物的C-N偶联有效地进行，以高收率得到N-芳基吡唑产物。发现3-三甲基甲硅烷基吡唑是偶联的极佳吡唑底物，相应的产物1-芳基-3-三甲基甲硅烷基吡唑也可作为合成N-芳基吡唑衍生物的很好模板，如在该区域的区域选择性卤化所证明的那样。吡唑环的3位，4位和5位。

• Zinc-Catalyzed Synthesis of Pyrazolines and Pyrazoles via Hydrohydrazination
  作者：Karolin Alex、Annegret Tillack、Nicolle Schwarz、Matthias Beller

  DOI：10.1021/ol800592s

  日期：2008.6.1

  A novel regioselective synthesis of aryl-substituted pyrazolines and pyrazoles has been developed. Substituted phenylhydrazines react with 3-butynol in the presence of a catalytic amount of zinc triflate to give pyrazoline derivatives. The resulting products are easily oxidized in a one-pot procedure to the corresponding pyrazoles.
