実験手順

To a solution of 2.16 g (7.8 mmol) of 3,6-di-tert-butylfluorene in 35 ml of THF, 5.0 ml (8.2 mmol) of a hexane solution of n-butyllithium was dropwise added in a nitrogen atmosphere with ice cooling, followed by stirring at room temperature for one night. To the resulting red solution, a solution of 2.16 g (10.6 mmol) of 3-(1,1,3-trimethylbutyl)-6,6-dimethylfulvene in 10 ml of THF was dropwise added in a nitrogen atmosphere with ice cooling, followed by stirring at room temperature for 5 days. After the reaction solution was diluted with 100 ml of ether, 50 ml of water was added. The separated organic phase was washed with water and a saturated saline solution, then dried over magnesium sulfate and filtered. From the filtrate, the solvent was removed under reduced pressure to obtain a liquid. The liquid was isolated and purified by column chromatography (silica gel, developing solvent: hexane) to obtain 2.80 g (5.80 mmol) of a white solid (yield: 74%). The analyzed values are given below.
