  Copper-catalyzed alkyne–aryne coupling reaction under microwave conditions: preparation of unsymmetric and symmetric di-substituted alkynes

  摘要：

  Several unsymmetric and symmetric alkynes were prepared excellent to modest yields by generating benzyne from the reaction of 2-(trimethylsilyl)phenyl triflate with CsF in the presence of Cul and terminal alkyne under microwave heating for 30 min at 150 degrees C. Using conventional heating, the reactions required 24 h reaction time. (C) 2009 Elsevier Ltd. All rights reserved.

  hydrocarbon based on phenalenyl unit acts as a catalyst for cross-coupling between aryl halides and aryl alkynes synthesizing a rich library of internal alkynes without any external stimuli. This protocol was extended to accomplish the Sonogashira-type coupling under transition-metal-free and solvent-free conditions.

  基于苯酚基单元的超还原奇数交替烃充当芳基卤化物和芳基炔之间交叉偶联的催化剂，合成丰富的内部炔烃库，无需任何外部刺激。该方案被扩展以在无过渡金属和无溶剂条件下完成 Sonogashira 型偶联。
