実験手順
To a solution of 8.00 g (59.6 mmol) of 6,6-diethylfulvene in 35 ml of ether, 60.0 ml (68.4 mmol) of an ether solution of methyllithium was dropwise added in a nitrogen atmosphere with ice cooling, followed by stirring at room temperature for one night. Then, 30 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 subjected to vacuum distillation (92° C./40 mmHg) to obtain 5.50 g (36.6 mmol) of a light yellow liquid (yield: 61%). The analyzed values are given below.
