New tricks for an old dog: The Pd‐catalyzed carbonylative α‐arylation of monoethyl potassiummalonates with aryl bromides and reactive aryl chlorides provides a simple and direct route to aryl β‐ketoesters. Because only stoichiometric amounts of carbon monoxide are employed, the method is ideal for the introduction of carbon isotopes into more complex structures.
