A series of new pyridinyliminophosphorane bidentate ligands with different steric environments [(2‐C 6 H 4 N)PPh 2 =NAr ( NPN )] and their methylpalladium complexes [PdClMe( NPN )] were prepared. From the crystal structure analysis it is evident that the alkyl ligands are always trans to the pyridinyl nitrogen donor, revealing a σ‐donating ability of the iminophosphorane. However, the two Pd−Cl bonds in [PdCl 2 ( NPN )] are essentially the same length. Cationic palladium complexes catalyzed the copolymerization of norbornene/ethylene as well as CO/norbornene.
