To 4.80 g (30.2 mmol) of dichloro(phenyl)borane, dissolved in 70 ml of diethyl ether, a suspension of 8.36 g (60.4 mmol) of trimethylsilylcyclopentadienyllithium in 100 ml of diethyl ether is slowly added at -78° C. The mixture is allowed to warm to room temperature in the cooling bath, and insolubles are filtered off. After concentrating the yellow filtrate to dryness in an oil-pump vacuum, 10.8 g of bis(trimethylsilylcyclopentadienyl) (phenyl)borane is obtained as a yellow viscous oil.
