Procedure

3.5 g of 2,4-bistrifluoromethylbenzylcyclopentadiene and 30 ml of hexane are charged, in an argon atmosphere, into a tailed test-tube equipped with magnetic stirring. 6 ml of a 2.5 M solution of butyllithium in hexane are then added. There is an immediate reaction with the development of heat and the formation of a yellow precipitate which is washed several times with hexane by decanting and finally dried. 3.0 g of the desired salt are obtained with a yield of 85%.
