Palladium, radically different: A wide range of polyfunctional aryl‐ and heteroarylmagnesium reagents undergo fast Kumada cross‐couplings (see scheme) with functionalized aryl bromides in the presence of a palladium catalyst and an alkyl iodide as additive. These reactions proceed by a radical pathway.
