The dimerization of 1-hexene was catalyzed by ten zirconocenes. High catalytic productivity was achieved via a two-step activation process, namely, the treatment of the zirconocene with triisobutylaluminum (TIBA) followed by methylaluminoxane (MAO). The z

Benzyl- and phenyl-cyclopentadiene have been shown to react with thallium ethoxide in ethanol to give the corresponding benzyl- and phenyl-cyclopentadienylthallium compounds in excellent yield.These reagents are air stable for brief periods, have extended shelf-lives, and have been shown to be superior starting materials for the synthesis of a variety of cyclopentadienylmetal complexes.
Chemistry of gem-Dihalocyclopropanes. XX. The Effect of Methyl and Phenyl Substituents on the Vinylcyclopropylidene-Cyclopentenylidene Rearrangement

Reactions of gem-dibromocyclopropanes of the general structure 1 with methyllithium have been studied.In the most cases cyclopentadienes and/or vinylallenes are the products formed.The results obtained give evidence of a profound substituent effect on the carbene-carbene rearrangement leading to cyclopentadienes.We believe the effect is essentially steric in origin.The results support the mechanism proposed for the rearrangement.
