Versuchsvorschrift

In accordance with the procedure of Example 5, 4.3 g (0.0134 mol) of hafnium tetrachloride are added at 55° C. under nitrogen over 30 minutes to a stirred mixture of 56 g of cumene, 5 g (0.027 mol) of ferrocene, 4.8 g (0.0358 mol) of aluminium chloride and 0.12 g (0.0045 mol) of aluminium powder. Working up is effected as in Example 4, affording 3.5 g (68.6% of theory) of hafnocene dichloride which melts at 228°-230° C.
