在DMF-H2O中，双苯并咪唑盐(1-7)、Pd(OAc)2和K2CO3的混合物可在短时间内高产率地催化Suzuki和Heck交叉偶联反应。特别是，Heck和Suzuki与芳基溴化物的反应的产率几乎是定量的。合成的双苯并咪唑盐(1-7)经~1H13C核磁共振、红外光谱和显微分析确证。版权所有©2010 John Wiley&Sons，Ltd.
A mixture of bis-benzimidazole salts (1–7), Pd(OAc)2 and K2CO3 in DMF H2O catalyzes, in high yield, the Suzuki and Heck cross-coupling reactions assisted by microwave irradiation in a short time. In particular, the yields of the Heck and Suzuki reactions with aryl bromides were found to be nearly quantative. The synthesized bis-benzimidazole salts (1–7) were identified by 1H13C NMR, IR spectroscopic methods and micro analysis. Copyright © 2010 John Wiley & Sons, Ltd.
