摘要
New asymmetrically substd. silyl-functionalised transition metal metallocenes are of formula (I) ÄR1R2X1Si(R3)aCpÜÄ(R4)aCpÜM(X2)n (I) where R1, R2 = alkyl or aryl; X1 = F, Cl, Br, I, p-tolylSO3, F3CSO3, F3CCO2 or H3CCO2; R3, R4 = alkyl, alkyl ether, aryl or aryl ether gps.; with 0 ≤ a ≤ 4; Cp = a cyclopentadienyl, indenyl, tetrahydroindenyl or fluorenyl gp.; M = a gp. 3-6 transition metal, esp. Ti, Zr or Hf; X2 = F, Cl, Br or I; n = 2 less than the oxidn. no. of M.
