Reaction Conditions

Reaction Steps

19.6 g (98 mmol) of tetraphthalonitrile, 21.6 g (196 mmol) of thiophenol, 17.1 g (294 mmol) of potassium fluoride and 100 ml of acetonitrile were fed into a 200 ml four-necked flask and the mixture was stirred at 50° C. for 12 hours. The temperature was then returned to room temperature, and the resulting yellow solid was filtrated. The resulting cake was washed with methanol and then with hot water to give 34.55 g of 3,6-difluoro-4,5-bisphenylthiophthalonitrile.
