Reaction Conditions

Reaction Steps

Following the procedure of Example 1, 1.1 g (6.2 mMoles) of anthracene and 42.7 g of cyclopentadiene are added to 10.94 g (450 mMoles) of fine magnesium powder in 300 ml of THF, followed by activation with 0.1 ml of methyliodide and by treatment for 3 hours in an ultrasonic bath. 56.9 g (33 ml=300 mMoles) of TiCl4 are then added dropwise, which initiates an extremely vigorous reaction and an increase in temperature to 69° C. After the addition, the mixture is allowed to cool to 23° C. and 14.8 g of a scarlet-red compound are obtained after 12 hours, being isolated by filtration. Another 69.1 g are obtained from the filtrate by concentration. Total yield: 83.9 g of C5H4 --C5H4Ti2 (C5H5)2Cl2 corresponding to 179.9 mMoles=66% of the theoretical.
