Ethylene Oligomerizations by Sterically Modulated Salicylaldimine Cobalt(II) Complexes Combined with Various Alkyl Aluminum Cocatalysts

A set of structurally modulated salicylaldimine cobalt(II) complexes have been synthesized and utilized them for ethylene oligomerizations in combination with various organoaluminum cocatalysts. All catalyst systems yielded α-olefins with butenes as major product. The catalytic activity and product...

Description
Summary:A set of structurally modulated salicylaldimine cobalt(II) complexes have been synthesized and utilized them for ethylene oligomerizations in combination with various organoaluminum cocatalysts. All catalyst systems yielded α-olefins with butenes as major product. The catalytic activity and product distribution were affected by the catalytic structure and reaction conditions. The formation of active species in these complexes under oligomerization conditions was investigated by UV-VIS spectroscopy and the results matched well with oligomerization results.
