Versuchsvorschrift

A mixture of 2-acetyl-7-bromofluorene (13.2 g.) and cuprous cyanide (8.2 g.) in quinoline (40 ml.) was heated to reflux for 40 minutes, cooled to 100° and poured into a mixture of ice-cold dilute aqueous ammonia and dichloromethane. The organic layer was separated, filtered to remove a yellow solid, washed with N-hydrochloric acid, dried over sodium sulphate and evaporated. The residual solid was recrystallised from ethanol containing a small amount of dimethylformamide to give 2-acetyl-7-cyanofluorene m.p. 182°-188°.
