摘要
研究了无铜、无配体、可回收利用的催化体系[Pd(OAc)2/TBAB]催化卤代芳烃与末端炔烃的Sonogashira交叉偶联反应,高产率地合成了一系列偶联产物,其结构经1H NMR和13C NMR表征。催化实验结果表明,Pd(OAc)2/TBAB可回收重复使用3次,催化活性基本不变。
Sonogashira cross-couplings of aryl halides with terminal alkynes were investigated using copper-free, ligand-free and reusable Pd （OAc）2/TBAB as the catalyst. A series of coupling compounds were synthesized in high yields. The structures were characterized by 1^H NMR and 13^C NMR. Pd（ OAc）2/TBAB could be recovered and reused three times without a loss of catalytic efficiency.
