摘要：

Tris(dimethylamido) peritaphenylcyclopentadienyl zirconium (I) has been prepared and characterized by NMR spectroscopy and X-ray crystallography. The structure reflects the strong p-d amido donation with short Zr-N distances and Zr-C distances that are longer than those in the 16 electron C5Ph5(C5H5)ZrCl2. The reaction of I with (R)-(+)-sec-phenethyl alcohol to form the alkoxide complexes proceeds rapidly to the spectroscopically characterized tris((R)-(+)-sec-phenethyl alkoxide) complex, suggesting an activating effect upon alkoxide substitution.
