The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(π-cinnamyl)Cl]2 enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this

By using [Ru(TTP)CO] [H2TTP = meso-tetrakis(4-tolyl)porphyrin] as catalyst and aryl azides as the nitrene source, the sp2(C–H) bonds of a series of indoles undergo oxidative C–N bond formation to give unique 2,3-diimination products in good to high yields.
the N-arylation of aromatic heterocycles like indoles and pyrroles is reported by a Pd nanocatalyst under ligand- and Cu-free conditions. The reaction conditions tolerate several functional groups and work very efficiently for aryliodides and bromides. Aryl chlorides are also successful as the coupling partners albeit with lower yields. The methodology is also applicable for the N-arylation of aliphatic
