A decarboxylative Mizoroki–Heck coupling of aryl halides with cinnamic acids has been developed in which the carboxylate group directs the arylation into its β‐position before being tracelessly removed through protodecarboxylation. In the presence of a copper/palladium catalyst, both electron‐rich and electron‐deficient arylbromides and chlorides bearing numerous functionalities were successfully
