• Palladium catalysis

An economic and novel ligand, cyclodiphosphazane [ClPN(t-Bu)](2) (1), was introduced in the palladium-catalyzed amination of unactivated aryl halides. The catalyst allows for the amination of aryl chlorides and bromides with secondary cyclic amines and anilines in good yields.
