Procedure

2.5 g of 4-trifluoromethylbenzylcyclopentadiene (10 mmoles) and 30 ml of hexane are charged, in an argon atmosphere, into a tailed test-tube equipped with magnetic stirring. The same procedure is then carried out as in paragraph 2 of example 1 above, using 4.5 ml of a 2.5 M solution of butyllithium in hexane. At the end, 2.1 g of the desired salt are obtained with a yield of 80%.
