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 characterized. The solid‐state structure of the complex was determined by single‐crystal X‐ray diffraction. As combined with methylaluminoxane (MAO), the complex displayed high catalytic activity for vinyl polymerization of norbornene. Copyright © 2005 John Wiley & Sons, Ltd.
