The codimerization of styrene with ethylene was studied using the catalyst system composed of bis (triphenylphosphine) σ-aryl (bromo) nickel (II) and trifluoroboron etherate in methylene dichloride. The codimerization takes place readily at 0° C under atmospheric pressure to give 3-phenyl-1-butene selectively. The reaction scheme was discussed on the basis of the product distribution during the course of reaction and its kinetics.
