Syntheses of etheno-bridged ansa-titanocene derivatives by the McMurry reaction Burger, Peter Novel olefin-linked biscyclopentadienyl ligands have been prepared by McMurry coupling reactions of benzoyl- and acetyl-cyclopentadienyl sodium. Reactions of the disodium salts with TiCl<sub>4</sub> or TiCl<sub>3</sub> · 3THF afford the alkene-bridged ansa-titanocene dichlorides. <sup>13</sup>C-NMR shifts to the bridge carbon atoms do not indicate any interaction between the olefin π-system and the metal. deposit-license Burger, Peter 1991 Brintzinger, Hans-Herbert Brintzinger, Hans-Herbert
