Bis(imino)-6,7-dihydro-5H-quinoline-cobalt complexes as highly active catalysts for the formation of vinyl-terminated PE waxes; steps towards inhibiting deactivation pathways through targeted ligand design.

ABSTRACT: A set of five related bis(imino)-6,7-dihydro-5H-quinoline-cobalt(ii) complexes, [2-(ArN = CPh)-8-(NAr)-C₉H₈N]CoCl₂ (Ar = 2,6-Me₂C₆H₃Co1, 2,6-Et₂C₆H₃Co2, 2,6-i-Pr₂C₆H₃Co3, 2,4,6-Me₃C₆H₂Co4, 2,6-Et₂-4-MeC₆H₂Co5), have been synthesized in reasonable yield by the template reaction of cobalt(ii) chloride hexahydrate, 2-benzoyl-6,7-dihydro-5H-quinolin-8-one and the corresponding aniline. The molecular structures of Co1 and Co4 highlight both the differences in the two imino-carbon environments (phenyl-capped chain vs. cyclic) and also the steric properties exerted by the bulky
