摘要
Novel olefin-linked biscylopentadienyl 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. C-13-NMR shifts of the bridge carbon atoms do not indicate any interaction between the olefin pi-system and the metal.
