Rare Earth–Transition Metal Cooperativity in the Ring-Opening Polymerisation of Tetrahydrofuran
A synergistic RECl3/[Cu(CH3CN)4]PF6 catalyst system enables the controlled, ring-opening polymerisation of THF at room temperature without the need of any additional initiators. High-molecular-weight PTHF (Mₙ = 209 kDa, Ð = 1.6) is obtained at low catalyst loadings, with tunable chain lengths via a targeted ligand addition.
