Bis(cyclopentadienyl)zirconium(IV) dichloride is used as a catalyst of the carboalumination of alkynes by trimethylaluminum to give an (alkenyl)dimethylalane, a versatile intermediate for further cross-coupling reactions for the synthesis of stereodefined trisubstituted olefins. This product can also be applied to prepare the Negishi reagent, Cp2Zr(η2-butene), which can be used as a source of Cp2Zr in oxidative cyclization reactions. Also, Cp2ZrCl2 reacts with lithium aluminum hydride to give Cp2ZrHCl Schwartz’s reagent. The Cp2ZrCl2/C2H5AlCl2 system was found to be an active catalyst for the polymerization of alkynes.
