Zusammenfassung
Novel olefin-linked biscyclopentadienyl ligands have been prepared by McMurry coupling reactions of benzoyl- and acetyl-cyclopentadienyl sodium. Reactions of the disodium salts with TiCl4 or TiCl3 · 3THF afford the alkene-bridged ansa-titanocene dichlorides. 13C-NMR shifts to the bridge carbon atoms do not indicate any interaction between the olefin π-system and the metal.
