Reaction Steps

24.8 g (106.5 mmol) of zirconium tetrachloride and 150 ml of toluene were placed under argon in a 0.5 l two-neck flask. The white suspension was cooled to −20° C. and a solution of 30.68 g (101.4 mmol) of diphenylboranyltrimethylsilylcyclopentadiene in 150 ml of toluene was added. The brown suspension was stirred at room temperature for 24 hours and filtered through a D3 frit. The filtrate was evaporated to dryness under reduced pressure. The brown residue was stirred a number of times with n-hexane, giving a brown powder. This was dried to constant weight under reduced pressure.
