Procedure

To a suspension of 1,3-bis(2,6-diisopropylphenyl)-iminoimidazoline (1.02 g, 2.5 mmol) and cyclopentadienyltitanium trichloride (0.55 g, 2.5 mmol) in toluene (20 mL) was added triethylamine (0.25 g, 2.5 mmol) at ambient temperature. After stirring for 2 hours, the thick yellow-orange suspension was filtered, and the filtrate evaporated to dryness to afford 1.31 g (89% yield) of NMR-pure 1,3-bis(2,6-diisopropylphenyl)-iminoimidazoline cyclopentadienyltitanium dichloride.
