From (+)-neomenthylcyclopentadiene and trimethylsilyl cyclopentadiene, a couple of prochiral zirconocenes have been prepared. Upon further reactions with nucleophiles these zirconocenes were transformed to chiral ones with chirality on the zirconium atom. The NMR spectra of these complexes manifested that the chiral ligand had exerted a considerable chirally inductive effect during the course of the nucleophilic substitution.
