A new diphosphinoamine ligand [Ph 2 PN(p-C 6 H 4 OMe)PPh 2 ] was prepared through aminolysis reaction of p-methoxyaniline with Ph 2 PCl in the presence of NEt 3 . Consequently, the corresponding nickel (II) diphosphinoamine complex [(p-C 6 H 4 OMe)N(PPh 2 ) 2 NiCl 2 ] was synthesized and characteriz
