Reaction Conditions

Reaction Steps

1.0 g (8.2 mmol) of 2,4-dimethylphenol in 20 ml of toluene/2 ml of THF was admixed at room temperature with 3.0 ml (8.2 mmol) of a 20% strength solution of butyllithium in toluene. The mixture was stirred for another 1 hour at 60° C. At room temperature, 1.9 g (4.0 mmol) of dimethylsilanediylbis(2-methylindenyl)zirconium dichloride were added as a solid. The suspension was stirred for 8 hours at 60° C. and subsequently filtered hot through Celite. After evaporation of the solvent to leave a volume of about 7 ml, the yellow solid which precipitated at −30° C. was filtered off and dried under reduced pressure. This gave 0.65 g (29%) of dimethylsilanediylbis(2-methylindenyl)zirconium monochloride mono(2,4-di-methylphenoxide) (5).
