palladium-catalyzed arylation of anisoles. During this research, the formation of a four-membered lithiumcycle followed by transmetalation to the corresponding palladacycle has been achieved, which is difficult to be obtained from palladium-catalyzed C–H activation processes. This approach has provided an alternative way of introducing functionalities to arenes such as anisoles, thioanisoles, and anilines
我们在这里报告了我们关于定向锂化和钯催化苯甲醚芳基化的最新发现。在这项研究中,已经实现了四元锂环的形成,然后金属转移到相应的钯环,这是钯催化的 C-H 活化过程难以获得的。这种方法提供了一种将官能团引入芳烃的替代方法,例如苯甲醚、苯甲硫醚和苯胺。与过渡金属催化条件下的反应相比,这种方法还具有出色的单选择性。
