Dicyclopentadienyl zirconium dichloride

Preparation. This hydride is prepared by reduction of dicyclopentadienyl-zirconium dichloride (zirconocene dichloride) with either LiAlH(0-r-Bu)3 or NaAlHj (OC2 H4 OCH3 >2... [Pg.176]

Metallocene catalysts, for example dicyclopentadienyl zirconium dichloride, in combination with the cocatalyst methylalumoxane, helped establish a regulated set of properties, making it possible to customize molar mass, molar mass distribution, tacticity, heat resistance, rigidity, hardness, cold impact strength, and transparency. Added to these advantageous physical properties is the reactivity of this catalyst... [Pg.22]

The addition of trialkylalanes to alkenes is also catalysed by dicyclopentadienyl-zirconium dichloride to afford hydroalumination products that undergo protonolysis to yield alkanes. Thus, reaction of oct-l-ene with Bu gAl with a catalytic quantity of cpaZrCl2 at 0 °C gives n-octane in 97 % yield. Reduction of alkenes containing hydroxyl, phenylthiolato, and bromo functions can also be reduced in the same way. ... [Pg.66]

Titanium bis-enolate 19, readily available by transmetallation of the lithium enolate of acetaldehyde with dicyclopentadienyl titanium dichloride (Cp2TiCl2), was characterized by a crystal structure analysis [53, 54]. Mono-enolates of titanium and zirconium 20 were obtained analogously from Cp2Ti(Me)Cl and... [Pg.100]
