  nickel‐catalyzed CH bond functionalization process with the assistance of a bidentate directing group. The reaction favors the CH bonds of β‐methyl groups over the γ‐methyl or β‐methylene groups. Additionally, a predominant preference for the β‐methyl CH bonds over the aromatic sp2 CH bonds was observed. Moreover, this process also allows for the effective functionalization of benzylic secondary sp3 CH bonds
