  名称：

  Reaction of cyclopentadienyl zirconium derivatives with sterically encumbered arylaluminum hydrides: X-ray crystal structure of (η5-C5H5)2(H)Zr(μ2-H)2Al(H)C6H2-2,4,6-But3

  摘要：

  The novel reactions between Cp2ZrMe2 (Cp=eta(5)-C5H5) and (Mes*AlH)(2) (Mes*=C6H2-2,4,6-Bu-3(t)) to afford Cp-2(H)Zr(mu(2)-H)(2)Al(Me)Mes* (1) and between Cp2Zr(Cl)H and [Mes*AlH3Li(THF)(2)](2) to give Cp-2(H)Zr(mu(2)-H)(2)Al(H)Mes* (2) are described. The X-ray crystal structure and NMR spectroscopy of 1 indicate that, in the crystalline product, a methyl group has been transferred from zirconium to aluminum, and the metals have been connected by two hydrogen bridges. The compounds Cp2ZrH2 and Mes*AlMe2 were also obtained as reaction products in the synthesis of 1. The aluminum center is four-coordinate in contrast to the five- or six-coordination observed in previously published complexes. Compound 2, which is believed to have a very similar structure to that of 1, was obtained in moderate yield as a colorless crystalline material. (C) 1999 Published by Elsevier Science Ltd.
