摘要:
A process for the preparation of a tridentate transition metal catalyst components incorporating pyridinyl bis-amino or monoamino ligand structures which do not require π bonding of the transition metal through the use of cyclopentadienyl rings. The ligand structure incorporates a heteroatom group that involves nitrogen in one organogroup and either oxygen or nitrogen in another organogroup. The process of preparing the catalyst component involves the reaction of a bis-amino or oxyamino pyridenyl ligand compound with an organo transition metal compound involving a tetrabenzyl ligand or other functional group ligands linked to a transition metal such as titanium zirconium or hafnium.
