摘要：A process for the dimerization of alpha-alkenes having 2 to 12 carbon atoms inthe presence of an alkanediol solvent and of a novel catalytic system formed bycombining:
(a) a palladium(II) compound,
(b) a chelate ligand comprising a compound containing at least two N coordinatingatoms which are connected through a chain comprising two C atoms, > 2.0 mol chelateligand per gram-atom Pd being used,
(c) a protonic acid, except hydrohalogenic acids, and
(d) a salt of Cu, Fe, Zn, Sn, Mn, V, Al or a Group VIB metal, except a halide.
