Abstract
A convenient and efficient protocol has been achieved for the cross-coupling of phenols and vinyl halides by a unique Ni/Cu catalytic system for the first time, where the reaction is catalyzed by Ni and Cu is involved in the transmetalation process. This procedure provides an easy access to a library of aryl-vinyl and aryl-styrenyl ethers.
摘要
一种方便、高效的酚与卤代乙烯交叉偶联的新方法，首次通过独特的镍/铜催化体系实现。该反应由镍催化，铜参与转金属化过程。此方法为芳基乙烯基和芳基苯乙烯基醚库的构建提供了一种简便的途径。
