Versuchsvorschrift

A solution of 67.8 mmol of lithiumfluorene in 50 cm3 of tetrahydrofuran is added to a solution of 11.4 g (67.8 mmol) of 6-methyl-6-phenyl-fulvene in 40 cm3 of tetrahydrofuran at room temperature. After the mixture had been stirred at room temperature for 2 hours, 60 cm3 of water were added. The substance which precipitated during this procedure was filtered off with suction, washed with diethyl ether and dried under an oil pump vacuum. 19.1 g (84.2%) of 2,2-cyclopentadienyl(9-fluorenyl)-ethylbenzene were obtained (correct elmemental analyses; 1H-NMR spectrum).
