Design of postmetallocene catalytic systems of arylimine type for olefin polymerization: XIV. Synthesis of (N-Allyloxyaryl)salicylaldimine ligands and their complexes with titanium(IV) dichloride
摘要:
By reaction of salicylaldehydes with bulky substituents in the positions 3 and 5 with o-, m-, and p-allyloxyaniline hydrochlorides in the presence of triethylamine a series of the corresponding (N-aryl)-salicylaldimines was obtained, which with TiCl2(OPr-i)(2) afforded complexes of titanium(IV) dichloride L2TiCl2.

The kinetic features of ethylenepolymerization on ten methylalumoxane-activated self-immobilized bis(phenoxyimine) complexes of titanium chloride of various structure containing oxyallyl functional groups were studied. The catalytic activity of the systems was determined in the temperature range 20–60 °C under ethylene pressure 0.4 MPa. The positions and structures of the oxyallyl group and substituents
