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
