nickel‐catalyzed CH bond functionalization process with the assistance of a bidentate directing group. The reaction favors the CH bonds of β‐methyl groups over the γ‐methyl or β‐methylene groups. Additionally, a predominant preference for the β‐methyl CH bonds over the aromatic sp2 CH bonds was observed. Moreover, this process also allows for the effective functionalization of benzylic secondary sp3 CH bonds
脂族酰胺的分子内脱氢环化反应是通过镍催化的CH键官能化过程以及双齿导向基团在未活化的sp 3碳原子上实现的。与γ-甲基或β-亚甲基相比,该反应更有利于β-甲基的CH键。另外,对于β-甲基℃的主要偏好在芳香属H键2 ç 观察H键。此外,这种方法还允许的苄型二次属有效的官能化3 Ç H键。
