A series of late-transition metal complexes supported with chlorinated bis(arylimino)pyridine ligands [2  Ar = 2  Ar = 2  Ar = 2  Ar = 4-Cl-2  Ar = 4-Br-2  6-(ArN=CCl)(2)C5H3N]MtCl(2) (Ar = 2  6-(Pr2C6H3)-Pr-i  6-Et2C6H3  6-Me2C6H3  6-Me2C6H2  6-Me2C6H2  4  Mt = Fe (1b)  Mt = Co (1c)  Mt = Fe (1d)  Mt = Fe (1e)  Mt = Fe (1f)  6-Me3C6H2  Co (2b)  Ni (3c)  Co (2d)  Co (2e)  Co (2f)) were synthesized. At the presence of methylaluminoxane (MAO)  Mt = Fe (1a)  Fe(II)- and Co(II)- based complexes were highly active towards ethylene polymerization  Co (2a)  affording polymers with bimodal and unimodal molar. mass distributions  Ni (3a)  respectively  while the Ni(II)-based complexes gave no polymer products. Moreover  the obtained polyethylenes were predominately saturated and vinyl-terminated for Fe(II)- and Co(II)-based complexes  respectively. Changing the ligand environment  polymerization parameters also posed a great influence on the catalytic activities and the properties of the resulting polymers. (C) 2014 Elsevier Ltd.
