Structural characterization of [κ2-(t-Bu)2PCH2C(O)C6 H5]PdMe(η2-C2H4)+ BAr′4-: A model for the catalyst resting state for ethylene polymerization

The Pd methyl-ethylene complex (P,O)Pd-Me(η2-C2H4)+ BAr′4- ((P,O) = phenacyldi-tert-butylphosphine; Ar′ = 3,5-(CF3)2C6H3) has been isolated and structural characterized by X-ray crystallography. The ethylene ligand is oriented perpendicular to the square plane and is cis to the methyl ligand. This compound closely models the resting state(s) for ethylene oligomerization /polymerization by such complexes.

Ethylene polymerization and ethylene/methyl 10-undecenoate copolymerization using nickel(II) and palladium(II) complexes derived from a bulky P,O chelating ligand

The article presented ethylene polymerization and ethylene/methyl 10-undecenoate copolymerization using nickel(II) and palladium(II) complexes. The complexes were derived from a bulky P,O chelating ligand. The catalysts employed for the polymerization studies were cationic nickel allyl complex and the palladium methyl complexes. It was concluded that the Ni(II) and Pd(II) complexes were active for the polymerization of ethylene but the Ni(II) allyl complex demonstrated very slow rates of initiation.
