摘      要：Six complexes of two series were studied as the catalyst precursors for CO/ethylene copolymerization by using catalytic evaluation method and EXAFS *** first series of the complexes has general formular (L)Pd(OCOCF3)2 in which L is DPPPr,DPPBu or *** second series of the complexes has general formular (DPPPr)Pd(A)2 in which A-is CF3COO-,P-CH3PhSO3-,Cl-or CH3COO-.The results showed that suitable ligands have relatively strong coordination ability to palladium(Ⅱ) *** anoins belonging to strong acids,have excellent stability on cationic palladium(Ⅱ),and easy to leave away to give coordination vacant to comonomers.
