A stable (amino)(phosphino)carbene as bidentate ligand for palladium and nickel complexes: Synthesis, structure, and catalytic activity

Two original complexes featuring an (amino)(phosphino)carbene η2-bonded to the metal have been obtained in 60% and 80% yields, by addition of the corresponding stable carbene to PdCl2(cod) and NiCl2(PPh3)2, respectively. Both complexes have been fully characterized including X-ray diffraction studies. The catalytic activity of the palladium complex has been evaluated for aryl amination reactions.
