| Abstract: | (C_(13)H_8)Si(CH_3)_2(C_5H_5)]was prepared with fluorenyl lithium,dimethyldichlorosilane and cyclopentadienylsodium with 51% total yield.Furthermore,a Si-bridged fluorenylidene cyclopentadienylidene zirconium complex(C_(13)H_8)Si(CH_3)_2(C_5H_5)]ZrCl_2 was synthesized by reaction of E(C_(13)H_8)Si(CH_3)_2(C_5H_5)]and ZnCl_4 with THF as a solvent under the Schlenk system.The reaction gave the target compound in 86% yield.The zirconium complex was characterized by ~1H NMR and ~(13)C NMR.After activated with methylaluminoxane,the metallocene complex showed a high catalytic activity for the ethylene and propylene polymerization reaction under atmosphere pressure.It was found that the title compound has a catalytic activity in the order of 10~3g/h,and the molecular weight of ethylene-propylene copolymers is about 10~4. |
