Versuchsvorschrift

A mixture of dibenzofulvene (1 g, 5.68 mmol), fluorene (0.93 g, 5.68 mmol) and EtONa (0.19 g, 2.79 mmol) in DMSO (20 mL) was heated at 90° C. for 16 hours, and was then cooled to room temperature. After carrying out the work-up, as reported in Example 8, 0.55 g of bis(9-fluorenyl)methane were obtained, with a yield of 28%.
