One, but not the same describes the painting “Double Me” (Michael Kvium) depicted on the cover which shows two men who appear at first to be competing. However, on closer inspection it appears that their shoes are joined together: Are they in fact cooperating? An analogy is drawn to two organocatalytic enantioselective arylation reactions presented in the Communications by K. A. Jørgensen and co‐workers on pages 5515 and 5520 ff. Both reactions feature quinone but follow noncovalent (left) and covalent (right) organocatalytic pathways. (Thanks to M. Kvium for permission to use the painting.)
