Abstract

Synthesis of [C ₆F ₅N=CH(2-O-C ₆H ₃-3-R)] ₂TiMeX (R: ^tBu; X: Br (2), R: ^tBu; X: Me (3), R: H; X: Me (4)) was achieved by the reaction of methylated titanium halides with sodium salts of the phenoxyimine ligands. These complexes can be activated with equimolar amounts of B(C ₆F ₅) ₃ or Ph ₃CB(C ₆F ₅) ₄ to form methyl cationic species, which, upon addition of a small amount of ethylene monomer allows room temperature observation of cationic polymeryl species.
