In accordance with the procedure of Example 4, 10 g (0.043 mol) of ZrCl4 are added at 60° C. under argon over the course of 1 hour and 10 minutes to a stirred mixture of 60 ml of mesitylene, 8 g (0.043 mol) of ferrocene and 5.7 g (0.043 mol) of sublimed AlCl3. Working up is effected as in Example 4, affording 20.1 g (83.4% of theory) of crude (η6 -mesitylene)-η5 -(cyclopentadienyl)-iron(II) tetrapnenylborate.
