Reaction Steps

10.0 g (31.0 mmol) of 2,7-dibromofluorene, 19.7 g (89.0 mmol) of 1-bromooctane, 25 ml of dimethylsulfoxide, 24.9 g (623 mmol) of sodiumhydroxide and 50 ml of water were added to a 200 ml three-necked flask equipped with a reflux condenser, and this mixture was heated to 80° C. After the dissolution of the 2,7-dibromofluorene was confirmed, 608 mg (2.66 mmol) of benzyltriethylammonium chloride was added, and the resulting mixture was heated and agitated for 20 hours.
