## Abstract The oxidative carbonylation of readily available (__Z__)‐(2‐en‐4‐ynyl)amines, catalyzed by the PdI~2~‐KI system, selectively afforded in satisfactory yields (40–95 %) either pyrrole‐2‐acetic ester or (pyridine‐2‐one)‐3‐acetic amide derivatives, depending on the susbtitution pattern of t
