N‐(2‐pyridyl)sulfonyl group acts as a removable directing group in the PdII‐catalyzed aryl CH ortho alkenylation of N‐alkyl aniline, benzylamine, and phenethylamine derivatives with electron‐poor alkenes. The products were obtained in high yields (70–90 %) and with complete regiocontrol. The mild reductive N‐sulfonyl removal enables the construction of a variety of nitrogen heterocycles.
