英文摘要
The indenyl ligand or cyclopentadienyl ligand have been believed as 'inert'. However, in this project, the indenyl ligand of bis(indenyl)zirconacyclopentadienes coupled with diene moiety in the same molecule to give fluorene derivatives in good yields. The size of the substituents on the cyclopentadienyl ligand effects the coupling greatly. The reaction of bis(cyclopentadienyl)zirconacyclopentadienes with titanium chloride gave low yield of the coupling product. However, in the t-butyl cyclopentadienyl ligand issue, the yield was quite high.
