ABSTRACT:
Alkyl groups in trialkyl aluminum are displaced by .alpha.-olefins in the presence of a nickel catalyst. The displaced alkyl group evolve as .alpha.-olefins. The displacement is fast and the catalyst is then poisoned with a catalyst poison such as lead to prevent undesired side reactions such as isomerization of .alpha.-olefins to internal olefins or dimerization to vinylidene olefins.
