Procedure

97.2 mg (0.372 mmol) of dichloromethylenebis(cyclopentadienyl)titanium was weighed out. Thereto 20 ml of dry toluene was added, and the mixture was cooled to a temperature of -78° C. 2.98 mmol of methylalumoxane (16-mer ) in toluene was added thereto dropwise with stirring, and the mixture was allowed to react at 50° C. for 6 hours. Then 20 ml of hexane was added to deposit a reddish brown solid. The solid was collected by filtration, recrystallized from toluene/hexane, and dried. The intended product was obtained in a yield of 71%.
