developed for the oxidativecoupling of non‐chelate‐assisted arenes with olefins in the presence of catalytic amounts of Cu(OAc)2⋅H2O as a co‐oxidant and oxygen as the terminal oxidant. The acid was an indispensable component in this system and played a very important role in the coupling reaction. This catalytic system was applied to the direct oxidativecoupling of a series of arenes and olefins and the corresponding
A [的RhCl(COD)} 2 ] /四氯化碳3 COOH系统用于非螯合辅助芳烃的氧化偶联在催化量的Cu的存在开发与烯烃(OAC)2 ⋅ ħ 2 O作为助氧化剂和氧气作为终端氧化剂。酸是该体系中必不可少的组分,并且在偶联反应中起着非常重要的作用。该催化体系用于一系列芳烃和烯烃的直接氧化偶联,相应的产物以高收率提供,具有特殊的化学和区域选择性。该反应为乙烯基芳烃提供了一种原子高效的途径,乙烯基芳烃广泛用于各种精细化学品中。
