摘要：
The effect of backbone-substituent of carbon-bridged diphosphine ligands of the type {Ph2PC(COOR)=C(COOR) PPh2} on the catalyst performance in ethylene oligomerization has been explored. The Cr precatalyst supported by the ligand {Ph2PC(COOMe)=C(COOMe)PPh2} (L1) achieved a high activity of 1800 kg/g Cr/h with a total selectivity of 90.8 % toward 1-hexene (77.3 %) and 1-octene (13.5 %) when activated with MMAO-3A. The catalytic system based on these ligands exhibited considerably high thermal stability, maintaining high activity even at 100 o C.
