SO(2) efficient: A three-component palladium-catalyzed coupling of aryl lithium compounds; sulfur dioxide (provided by the easy-to-handle solid surrogate, DABSO); and aryl, heteroaryl, and alkenyl (pseudo)halides yields a diverse library of sulfones. An electron-poor XantPhos-type ligand suppresses aryl-aryl exchange and is key to obtaining high yields.
