Design of Schiff Base-Like Postmetallocene Catalytic Systems for Polymerization of Olefins:X.Synthesis of Phenoxy Imino Ligands with Bulky Substituents

摘要

Reactions of primary amines with salicylaldehydes containing bulky substituents(tert-hutyl,2-phenylpropan-2-yl,triphenylmethyl)in positions 3 and 5 gave a number of new Schiff bases as ligands for complex formation with transition metals.
