  用于末端炔烃均聚和交叉偶联反应的铜基三元低共熔溶剂

  摘要：

  本文合成了一套铜基三元低共熔溶剂（Cu-DES），并将其应用于末端炔烃的格拉泽型均聚和交叉偶联。这些反应在无外源配体、无碱和无添加剂的条件下发生，并在温和条件下提供令人满意的优异产率（高达 99%）。Cu-DES可以回收8次，唯一的副产物是水，完全符合绿色化学原理。

  for the homo- & cross-coupling of terminal alkynes. Excellent functional group tolerance and good yields were observed with oxygen as an oxidant in an isopropanol solution (or as additive) under ambient conditions. Furthermore, the composite catalyst shows good recyclability and can be recovered simply and reused several times without significant loss in its catalytic activities.

  日期：2013.7

  Copper-catalyzed oxidative coupling reactions of terminal alkynes have been performed at room temperature by using enaminone as effective ligand. Both symmetrical and unsymmetrical 1,3-diynes bearing various functional groups have been synthesized in moderate to excellent yields via homo- and cross-coupling reactions. (C) 2013 Elsevier Ltd.
