Palladium-catalyzed amination reactions of aryl halides are indispensable tools for the synthesis of compounds with NÀ C (sp2) linkages.[1–4] Iodides and electronically activated bromides can be successfully transformed by employing simple palladium salts. Aryl chlorides, however, are arguably the most useful single class of substrates because of their lower cost and the wider diversity of available compounds. The conversion of aryl ...
