Abstract

The reaction of 1,1-bis(η<sup>5</sup>-cyclopentadienyl)-1-zirconacyclopenta-2,4-dienes with propargyl halides in the presence of a catalytic or a stoichiometric amount of CuCl afforded benzene derivatives. This reaction involves S<sub>N</sub>2' type of attack of organocopper intermediate to propargyl halide followed by intramolecular carbometallation, and coupling with the second molecule of propargyl halide. <p>
