Abstract

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.

Key words: Fulvene, Benzylsodium, Metallocene, Addition reaction
