Replacing the director: A bipyridinyl ligand with an aliphatic side chain determines the regioselectivity of copper‐catalyzed CH oxidation by intramolecular effects. Because the aliphatic chain is attached through an esterlinkage, the catalytic cycle can in principle be closed by transesterification. Ion‐mobility mass spectrometry and isotopic labeling provide mechanistic insight not available from
