The reaction of ω-alkenyl substituted zirconocene dichloride complexes with two equivalents of n-butyllithium is strongly influenced in the presence of alkenes and alkynes. Metallacyclic zirconocene complexes of novel structures are obtained. The additives alkenes and alkynes compete with the ω-alkenyl substituents and the intermediate 1-butene for the formation of a metallacyclic structure. The reaction
