Abstract
It has been shown that the bis(trimethylsilyl)acetylene complex of zir conocene Cp2Zr(THF)(Me3SiC2SiMe3) (1) and the binuclear sigma-alkenyl complex of zirconium {Cp[mu-(eta1:eta5-C5H4)]Zr[C(SiMe3)=CH(SiMe3)]12 (2) readily react with carbon dioxide at room temperature to form the dimeric zirconafuranone metallacycle [Cp2ZrC(SiMe3)=C(SiMe3)C(O)O]2(3) . Under similar conditions the reaction of Cp2Zr(THF)(Me3SiC2SiMe3) an d {Cp[mu-(eta1:eta5-C5H4)]Zr[C(SiMe3)=CH(SiMe3)]}2 with water affords the zirconoxane complex [Cp2ZrC(SiMe3)=CH(SiMe3)]2O (4). The structure s of the obtained complexes have been established by X-ray structure a nalysis.
