8-Quinolinol (1.45 g, 0.010 mol) is added to a three-neck flask with heptane (30 mL), and the mixture is stirred under nitrogen at 25 to 40° C. for 0.5 h. It becomes a pale yellow suspension. Titanium tetrachloride (10 mL of 1.0 M solution in heptane, 0.010 mol) is added dropwise to the suspension. After stirring at 25° C. for 2 h, solvents are removed under vacuum. The product is washed with heptane (30 mL), and the washings are decanted. The residue is dried under vacuum for 1 h, and is then recrystallized from a mixture of hydrocarbon solvents to give purple crystals of 8-quinolinoxytitanium trichloride (2.85 g, 95%).
