Abstract: Dialkylfulvenes and 6,6-polymethyleneftilvenes only undergo exocyclic double-bond addition with treatment of benzylsodium.Twentv-two novel titanocenes and zirconocenes with chiral or achiral substituents have been synthesized by complexation of substituted cyclopentadienyl anions obtained from the above reactions with TiCl4, ZrCl4 or (CpTiCl2)2O.Reaction mechanism and 1H NMRspectra have been discussed.
