Synthesis, Characterization and Polymerization Behavior of {(1 R, S )‐2‐(η 5 ‐9‐Fluorenyl)‐1‐[η 5 ‐(1 R,S )‐indenyl]‐1‐phenylethane}zirconium dichloride and {(1 R,S )‐Cyclohexyl‐2‐(η 5 ‐octahydro‐9‐fluorenyl)‐1[η 5 ‐tetrahydro‐(1 R,S )‐indenyl]ethane}zirconium Dichloride

Epoxystyrene ( 1a ) were converted into their corresponding alcohols, 2a–c , by treatment with either fluorenyl‐ or indenyllithium. These alcohols were then further converted into their trifluoromethanesulfonate derivatives, 3a–c . Subsequent reaction of the triflates with fluorenyl‐, indolyl‐, or tetraphenylcyclopentadienyllithium resulted in formation of 2‐(9‐fluorenyl)‐1(1‐indenyl)‐1‐phenylethane ( 4a ), and 1‐(9‐fluorenyl)‐2‐(5‐tetraphenylcyclopentadienyl)ethane ( 4c ). The ansa ‐metallocene (1‐( R,S )‐2(η 5 ‐9‐fluorenyl)‐1‐[η 5 ‐1( R,S )‐indenyl]‐1‐phenylethane]ZrCl 2 ( 5a ) was prepared from the dilithio salt of 4a . Hydrogenation of 5a with H 2 /PtO 2 leads to {1( R,s )‐cyclohexyl‐2‐(η 5 ‐octahydro‐9‐fluorenyl)‐1‐[η 5 ‐tetrahydro‐1( R,S )‐indenyl]ethane]ZrCl 2 ( 6a . The complexes 5a and 6a were activated with methylalumoxane (MAO) and used for propene polymerization. The solid state structures of 4b, 4c , and 5a are reported.
