Diethyl Ether → HCID 178440600, compound

Participants

Reaction Steps

5.8 ml (5.8 mmol) of a diethyl ether solution of methyllithium were added dropwise under ice cooling under nitrogen to a THF (20 ml) solution including 1.0 g (2.36 mmol) of 1-cyclopentadienyl-1-(2,7-di-tert-butylfluorenyl)cyclohexane synthesized in the above-mentioned (2), followed by stirring at room temperature for 7 hours. Next, the THF was distilled off under nitrogen, and the resultant solid was washed with hexane and then dissolved in dichloromethane cooled to −78° C. To this solution, zirconium tetrachloride 2THF complex (0.81 g, 2.15 mmol) dissolved in dichloromethane was added at −78° C., and after stirring for 24, the temperature of the solution was slowly returned to room temperature.
