摘要：

Substituted zirconocene dichlorides react with vinyl lithium with formation of zirconacyclopent-2-enes, Cp2ZrCH=CHCH2CH2, or zirconocene butadiene complexes, Cp2Zr(C4H6). The compounds obtained were characterized by their H-1 and C-13 n.m.r. spectra. The Zr-91 n.m.r. chemical shifts of substituted zirconocene dichlorides correlate with the bond angles Cp'-Zr-Cp' and Cl-Zr-Cl respectively. They can be used to estimate the reaction behaviour of zirconocene dichlorides.
