Abstract:
A process for producing a linear &agr;-olefin which comprises:reacting a feed comprising a stoichiometric excess of a terminal Cn olefin with ethylene in the presence of a transition-metal based catalyst selected from the group consisting of chromium trimerization catalysts, metal (II) &agr;-diimine complexes, pyridine bisimine iron or cobalt complexes, pseudotetrahedral nickel complexes, Ni-thiolene catalysts and neutral nickel (II) complexes bearing bidentrate monoanionic ligands to produce a Cn+2 linear &agr;-olefin, wherein said catalyst exhibits a Schulz-Flory constant of less than about 0.8 as observed for ethylene oligomerization and wherein n is an integer between about 3 to 20.
