dc.description.abstractThe position of the sulfur atom in the thienyl group of 6-(thienyl)-2-(imino)pyridine ligands stronglyaffects the catalytic activity of the corresponding tetrahedral high-spin dihalide CoII complexes in theoligomerization of ethylene to R-olefins upon activation with methylaluminoxane (MAO). Complexeswith the sulfur atom in the 3-position of the thienyl ring catalyze the selective conversion of ethylene to1-butene, while catalysts containing thien-2-yl groups give C4-C14 R-olefins. In situ EPR experimentsshowed the occurrence of a spin state changeover with the formation of low-spin CoII species uponactivation of the catalyst precursors by MAO. DFT calculations suggest that only thien-2-yl rings allowfor the coordination of the sulfur atom to the cobalt center in the MAO-activated systems.en_US
