Niederdruck‐Oligomerisation von Mono‐Olefinen mit löslichen Nickel/Aluminium‐Bimetallkatalysatoren, Teil II Reaktionskinetische Untersuchungen über die Dimerisation von Propen

The kinetics of the dimerization of propene in organic solvents under the influence of a homogeneous catalyst containing π‐tetramethylcyclobutadiene‐nickel dichloride and a prereacted mixture of ethylaluminiumdichloride and tri‐n‐butylphosphin are reported. The primary reaction products are: 2‐methyl‐1‐pentene, 4‐methyl‐2‐pentene (cis/trans), 2,3‐dimethyl‐1‐butene and 2‐Hexene (cis/trans) The results are in accordance with a coordinative mechanism on nickel. New results on the reaction between ethylaluminiumdichloride and O, N and P containing electrondonors are also discussed.
