Synthesis, Characterization and Mechanistic studies of Palladium(II) complexes containing tetradentate amine ligands for CO/ethylene copolymerization

초록

In order to investigate mechanistic aspects of palladium-catalyzed copolymerization of CO and ethylene to give polyketone polymers. New palladium(II) complexes containing Tri- and tetradentate amines were prepared as catalyst precursors. These complexes were characterized by 1H, 13C NMR, GC/MS and elemental analysis. Synthesis strategy and spectroscopic properties are discussed. Effect of substituent chain length(n=1,2), and physical properties of polymers are also discussed.
