Abstract

Epoxystyrene (la) and oxirane (Ib) 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 Inflates with fluorenyl-, indolyl-, or tetraphenylcyclopentadienyllithium resulted in formation of 2-(9-fluorenyl)-l-(l-indenyl)-l-phenylethane (4a), l-(9-fluorenyl)-2-(l-indolyl)-l-phenylethane (4b) and l-(9-fluorenyl)-2-(5-tetraphenylcyclopentadienyl)ethane (4c). The ansa-metallocene {l(ß,S)-2-(η5-9-fluorenyl)-1-[η 5-1(R,S)-in-denyl]-l-phenylethane]ZrCl2 (5a) was prepared from the dilithio salt of 4a. Hydrogénation of 5a with H2/PtO2 leads to (l(fl,S)-cyclohexyl-2-(η5-octahydro-9-fluorenyl)-l-[η 5-tetrahydro-l(A,S)-indenyl]ethane)zZrCl2 (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.
