Nickel-catalyzed product-controllable amidation and imidation of sp3 C-H bonds in substituted toluenes with sulfonamides

A nickel-catalyzed product-controllable imidation and amidation of sp(3) C-H bonds in substituted toluenes with sulfonamides were developed. Based on the change of the reaction time and atmosphere from N-2 to O-2, this reaction proceeded in high yields and excellent selectivity under different conditions. Mechanistic details were also described.
