実験手順

Under a nitrogen atmosphere, a 100-mL Schlenk flask was charged with 1.04 g (1.45 mmol) of dibenzylmethylene(cyclopentadienyl)(2,7-di[p-tolyl]-3,6-ditert-butylfluorene) and 60 mL of dehydrated diethyl ether, and the mixture was stirred. This mixed slurry solution was cooled in an ice bath, and 2.00 mL (3.20 mmol) of a 1.60 mol/L hexane solution of n-butyllithium was added. The mixture was stirred for 51 hours while gradually warming to room temperature. This red-orange reaction solution was cooled to −78° C. in a dry ice/methanol bath, and then 0.363 g (1.60 mmol) of zirconium tetrachloride was added. Subsequently, the mixture was stirred for 43 hours while gradually warming to room temperature to obtain an orange colored suspension. The solvent was removed by distillation under reduced pressure. Under a nitrogen atmosphere, the residue was dissolved in n-hexane, the liquid was passed through a glass filter filled with Celite, insolubles were washed with n-hexane, and the orange powder insoluble in n-hexane was subjected to extraction with dichloromethane. The solvent in which the dichloromethane-solubles were dissolved was distilled off. The residue was washed with diethyl ether/n-hexane to obtain a target product as an orange powder (yield 744 mg (58%)). The target product was identified by 1H-NMR and FD-MS spectroscopy.
