In this paper, we describe a Re2O7-mediated ring-opening arylation of unactivated arylcyclopropane because of its functionalization with various arenes via Friedel–Crafts-type reactivity. This protocol allows facile access to functionalized 1,1-diaryl alkanes and is characterized by a broad substrate scope, mild reaction conditions, high efficiency, and high atom economy. Both density functional theory
在本文中,我们描述了未活化的芳基
环丙烷的Re 2 O 7介导的开环芳基化,因为它通过弗里德尔-克拉夫茨型反应性与各种
芳烃进行官能化。该方案可以方便地获得功能化的1,1-二芳基
烷烃,具有底物范围广、反应条件温和、效率高和原子经济性高的特点。进行密度泛函理论计算和
氘标记实验来证明HFIP在该转化中不可或缺的作用,并指出Re 2 O 7介导的开环是速率决定步骤。
