Ethylene/allyl monomer cooligomerization by nickel/phosphine–sulfonate catalysts

Abstract

Nickel(II) complexes bearing a phosphine-sulfonate ligand, [(R(2)PC(6)H(4)SO(3))NiMe(2,6-lutidine)] (R = cyclohexyl, 2-MeOC(6)H(4), and 2-[2',6'-(MeO)(2)C(6)H(3)]C(6)H(4), were synthesized and applied as catalysts for the cooligomerizations of ethylene and allyl monomers.
