Investigations into the mechanism of activation and initiation of ethylene polymerization by bis(imino)pyridine cobalt catalysts: Synthesis, structures, and deuterium labeling studies

The activation of bis(imino)pyridine cobalt(II) precatalysts by MAO leads initially to a bis(imino)pyridine cobalt(I) cationic species with no cobalt-C(alkyl) bond into which insertion can occur. Mechanistic studies have shown that the initiation of polym

Experimental and computational study of β-H transfer between cobalt (I) alkyl complexes and 1-alkenes

Bis(imino)pyridine cobalt(I) alkyl complexes react with 1-alkenes by β-hydrogen transfer, providing a model reaction for the study of a commonly encountered chain transfer process in polymerization and oligomerization catalysis. The influence of steric effects on reaction rates is described. The theoretical models largely agree with the experimentally determined structures, provide a more detailed view of the species involved, and are consistent with the observed reactivities. Both experiment and theory support a stepwise pathway involving a cobalt-hydride intermediate.

The electronic structure of (diiminopyridine)cobalt(I) complexes

DFT calculations show that square-planar LCoIR complexes of a diiminopyridine ligand are best regarded as containing low-spin CoII antiferromagnetically coupled to a ligand radical anion. The lowest triplet state, corresponding to a 3dz2→π* excitation, is calculated to be only a few kcal/mol above the ground state, and is thermally accessible. The anomalous 1H NMR chemical shifts of the LCoR complexes are suggested to be due to thermal population of the triplet state at room temperature. Wiley-VCH Verlag GmbH & Co.
