conditions using PdCl2 as catalyst, MeOHPhMeH2O as solvent and K2CO3 as base effectively suppressed the formation of homo‐coupling product and afforded moderate to good yield of the desired unsymmetrical coupling product. This reaction represents a Suzuki‐type sp2(CB)–sp(CX) cross‐coupling. Copyright © 2011 John Wiley & Sons, Ltd.
描述了PdCl 2催化的芳基
硼酸的直接炔基化反应,生成二芳基
乙炔。使用的PdCl的最佳条件2为催化剂,MeOH中的PhMe ħ 2 O作为溶剂和K 2 CO 3作为碱有效地抑制均聚物偶联产物的形成时,可以得到适度的到所需的不对称偶合产物的良好的产率。该反应代表铃木型sp 2(CB)–sp(CX)交叉偶联。版权所有©2011 John Wiley&Sons,Ltd.
