Abstract

Examples of the title complexes have been prepared through two complementary routes. Spectral analysis indicate that they are best formulated as Zr analogues of Tebbe's reagent, Cp₂TiCH₂AlClMe₂. Single-crystal X-ray diffraction analysis of Cp₂ZrCH(CH₂-t-Bu)AlCl(i-Bu)₂at -100 °C confirms this result: space group C ⁵₂h—F2/n (No. 14), a = 19.779 (3) A, b = 14.055 (3) A, c = 9.086 (2) A, β= 90.12 (2)°, V = 2526 (2) A, and Z = 4. The final conventional and weighted agreement indices on F₀for 4306 reflections with F₀ ²> 3σ(f02) are 0.035 and 0.040. Both Zr and A1 show pseudotetrahedral coordination. The Zr—C bond length, 2.158 (2) A, indicates significant Zr=C bonding.
