The first rare earth organometallic complex of 1,4,7-trithiacyclononane: a precursor to unique cationic ethylene and α-olefin polymerisation catalysts supported by an all-sulfur donor ligand

Abstract

[Sc([9]aneS₃)(CH₂SiMe₃)₃], the first rare earth organometallic complex of 1,4,7-trithiacyclonane, is a precursor to ethylene and α-olefin polymerisation catalysts upon activation with BAr^F₃ or [CPh₃][BAr^F₄] (Ar^F = C₆F₅); these are the first cationic rare earth organometallic catalysts supported by an all-sulfur donor ligand.
