摘要：

The titanium complexes [eta(5):eta(1)-C5Me4(CH2)(3)O]TiR2 (R = CI, Me, CH2Ph, CH2CMe3, CH2SiMe3), with a linked Cp-alkoxide ancillary ligand, have been prepared in good yield. Cationic [C5Me4(CH2)(3)O]Ti(eta(2)-CH2Ph)(+) catalyzes the polymerization of propene to atactic polypropene. B(C6F5)(3) reacts with [C5Me4(CH2)(3)O]Ti(CH2SiMe3)(2) by Me abstraction from one of the CH2SiMe3 groups accompanied by an, attack of the ligand alkoxide functionality on the Si atom of this group.
