Zirconium chloride (ZrCl4), (T-4)- → HCID 178440793, compound

Participants

Reaction Steps

A solution of 1.2 g of 4-t-butylphenylcyclopentadienyllithium (0.0059 mole) in 20 ml tetrahydrofuran was slowly added at room temperature to a solution of 0.685 g of zirconium tetrachloride (0.0029 mole) in 50 ml tetrahydrofuran. After stirring the solution for 2 hours, the tetrahydrofuran was removed by evaporation leaving a residue. The resulting residue was taken up in hot toluene. Any undissolved material was removed by filtration and a resultant clear solution was evaporated to dryness. The solid residue obtained from the evaporation to dryness was taken up in dichloromethane. Undissolved, off-white solids were removed by centrifugation and decantation. The clear solution was once again evaporated to dryness yielding bis[(4-t-butylphenyl)cyclopentadienyl]zirconium dichloride as a yellow solid material. Spectral data from a proton-NMR is consistent with the product obtained.
