Procedure

60 ml dried diethylether and 5.34g of zirconocene dichloride were mixed and stirred at -20° C. in an argon atmosphere. 1.5 M methyl lithium was added little by little to this mixture and stirred for 70 minutes. The mixture was further stirred at 0° C. for 30 minutes, and the diethylether was removed whereby a white solid was obtained. The white solid thus formed was sublimated to give zirconocene dimethyl.
