Versuchsvorschrift

Fluorene (15.0 g, 90.4 mmol), n-BuLi (48.1 ml, 120 mmol, 2.5 M in hexane), RX=iodomethane (19.3 g, 136 mmol). 40 was isolated as a yellowish waxy solid (16.2 g, quant.). The analytical data were identical to those in the literature (M. A. Schmidt, H. G. Alt, W. Milius, J. Organomet. Chem. 1996, 525, 15).
