of our study on the formation of a complex having a zirconium-silicon bond, we found that zirconium-silenecomplex 7 was formed from Cp2ZrCl2 and Me2PhSiLi. In the presence of alkyne, diarylalkyne reacted with silene coordinated with zirconium to give silazirconacyclopentene 8. On the other hand, dialkylalkyne inserted into a zirconium-silenecomplex gave silazirconacyclopentene 9. Hydrolysis of 8 or
