A simple catalyst system consisting of Pd(OAc)2 and 3‐nitropyridine for the aerobic oxidative Heck coupling of cyclic enones, in particular challenging unsubstituted cyclic enones, with simple arenes by CH activation was investigated. This novel method was applied to various functionalized arenes and cyclic enones and allowed the synthesis of β‐aryl cyclic enones in modest to high yields.
