Versuchsvorschrift
Meanwhile, n-butyl lithium (26 ml, 0.042 mol) was slowly added to a solution of 1,2,3,4-tetramethylcyclopentadiene (5 g, 0.041 mol) in 100 ml of THF at −78° C. and the mixture was stirred for 2 hours. Then, the solvent was removed and the resultant product was washed with hexane and dried to obtain tetramethylcyclopentadienyl lithium (yield 76%).
