1H NMR characterization of intermediates formed by the activation of zirconocenes with methylaluminoxane at high Al/Zr ratios
Abstract
Cation-like intermediates formed by the activation of zirconocenes L2ZrCl2 [L2 are cyclopentadienyl (Cp), indenyl (Ind) and fluorenyl (Flu) ligands] with methylaluminoxane (MAO) at high Al/Zr ratios were characterised by 1H NMR spectroscopy.
