Abstract
A method for preparing a nickel-containing composition, and a composition prepared by such method, are disclosed including the steps of: a) mixing a phosphorous compound with a nickel complex having nickel bonded to a heteroatom to thereby form a nickel-phosphorous-containing mixture; and b) contacting the nickel-phosphorous-containing mixture with a supported partially hydrolyzed alkylaluminum compound, thereby forming such nickel-containing composition. Use of such nickel-containing composition in the dimerization of propene is also disclosed.
