摘要：

Various titanium complexes of the type Cp'Ti(OAr)Cl-2 (Cp' = cyclopentadienyl; OAr = aryloxy) could be prepared in high yields from Cp'TiCl3. These complexes show remarkable catalytic activities for alkene polymerization with MAO or (AlBu3)-Bu-i-Ph3CB(C6F5)(4): (C-5-Me-5)Ti(O-2,6-(Pr2C6H3)-Pr-i)X-2 (X = Cl (2b), Me (8b), CF3-SO3 (9b)) showed the highest activities. The bond angle Ti-O-C (phenyl group) in 2b (173.0 degrees) is significantly different from those for other complexes (162.3-163.1 degrees).
