Cost‐effective and air‐stable high‐valent cobalt(III)‐catalyzed weakly coordinating, ketone‐directed regioselective mono‐alkenylation of arenes and heteroarenes with alkenes is demonstrated. Various electron‐rich and electron‐deficient arenes are tolerated under the reaction conditions, providing E‐alkenylated products exclusively. The tert‐butyl‐acrylates serve as an acrylic acid surrogate to provide

A good neighborhood! The metal‐catalyzed oxidativeCH functionalization of electron‐rich arenes is well‐established, but analogous reactions of electron‐poor substrates are rare. A new application makes use of common electron‐withdrawing functional groups (COMe, CONH2, CONEt2) in the rhodium‐catalyzed oxidative Heck reaction to generate complex organic molecules. Cp*= η5‐C5Me5.
