摘要：Disclosed is a process for the production of chemical intermediates by the crossdimerization of two compounds containing carbon-carbon double bonds, wherein saidprocess is catalyzed by a nickel II catalyst which is a complex with &eegr;.sup.3 carbon-based allyl or substituted allyl, trisubstituted phosphine, and a weakly coordinatingligand. This catalyst may be used to selectively cross- dimerizes ethylene and methylacrylate to give methyl 4-pentenoate, a nylon 6,6 intermediate.
