Ligands and catalyst systems thereof for ethylene oligomerisation to linear alpha olefins. |
摘要 |
Mixed bis-imine pyridine ligands of formula (I), wherein Z<SUB>1</SUB>, which is different from Z<SUB>2</SUB>, is an optionally substituted aryl group; and Z<SUB>2 </SUB>comprises an optionally substituted heterohydrocarbyl moiety, or an optionally substituted aryl group in combination with a metal, said optionally substituted aryl group being pi-co-ordinated to the metal; mixed bis-imine pyridine complexes comprising a ligand of formula (I); mixed ionic bis-imine pyridine complexes comprising a ligand of formula (I); and processes for the production of alpha olefins from ethylene, using said complexes. |
