An intermolecular C(sp 3 )H amination using a Pd 0 /PAr 3 catalyst was developed. The reaction begins with oxidative addition of R 2 NOBz to a Pd 0 /PAr 3 catalyst and subsequent cleavage of a C(sp 3 )H bond by the generated PdNR 2 intermediate. The catalytic cycle proceeds without the need for external oxidants in a similar manner to the extensively studied palladium(0)‐catalyzed CH arylation reactions. The electron‐deficient triarylphosphine ligand is crucial for this C(sp 3 )H amination reaction to occur.
