Catalytic aromatic amination was achieved in water under heterogeneous conditions by the use of palladium complexes anchored to the amphiphilic PS-PEG resin with little palladium leaching to provide a green and clean (metal-uncontaminated) protocol for the preparation of triarylamines, including the optoelectronically active N,N,N',N'-tetraaryl-1,1'-biphenyl-4,4'-diamines (TPDs).
