摘要：

It has been shown that the zirconocene complex Cp2Zr(THF) (Me3SiC2SiMe3) readily reacts with disubstituted butadiynes R1C=CC=CR2 (R1 = R2 = SiMe3; R1 = SiMe3, R2 = (t)Bu or Ph) to form the dimeric symmetrical complex [Cp2Zr(mu-eta1:eta2-C=CSiMe3)]2 (2) and doubly acetylide-bridged, unsymmetrical complexes [Cp2Zr(mu-eta1:eta2-C=CSiMe3) (mu-eta1:eta2-C=C(t)Bu)ZrCp2] (3) and [Cp2Zr(mu-eta1:eta2-C=CSiMe3) (mu-eta1:eta2-C=CPh)ZrCp2] (4), respectively. The structure of the products has been established by X-ray structure analyses.
