Strong competition: A method for the meta‐selectivearylation of the highly versatile α‐aryl carbonyl motif using diaryliodonium salts is described. In this CuII‐catalyzed process the remote carbonyl group is capable of overpowering even strongly para‐directing functionalities to form the elusive meta‐products (see scheme). Remarkably, the arylation process can also operate under metal‐free conditions
