Design of Postmetallocene Catalytic Systems of Arylimine Type for Olefin Polymerization: XVIII. Synthesis of N-Arylsalicylaldimine Ligands Containing meta-or para-Diallylamino Group and Their Titanium(IV) Complexes

详细

Salicylaldehydes containing a tert-butyl or 2-phenylpropan-2-yl group in the 3-position reacted with N,N-diallyl-p-and -m-phenylenediamines in methanol to give the corresponding Schiff bases which were used as ligands to obtain titanium(IV) complexes with the composition L₂TiCl₂ by reaction with diisopropoxytitanium dichloride.
