摘要：

A new spin on polymers: The title cations comprise low-spin CoII centers with neutral bis(imino)pyridine chelating ligands. These complexes serve as single-component ethylene polymerization catalysts (see scheme) and offer insight into the mechanism of chain growth and catalyst deactivation, which occurs by forming inactive cationic bis(imino)pyridine cobalt complexes with a diethyl ether ligand. © 2011 Wiley-VCH Verlag GmbH & Co.
