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°).
