Various titanium complexes of the type Cp′Ti-(OAr)Cl2 (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 AliBu3-Ph3CB(C6F5) 4: (C5-Me5)Ti(O-2,6-iPr2C 6H3)X2 (X = Cl (2b), Me (8b), CF3-SO3 (9b)) showed the highest activities. The bond angle Ti-O-C (phenyl group) in 2b (173.0°) is significantly different from those for other complexes (162.3-163.1°).
