実験手順
86.0 g (0.51 mole) of 5-chloro-1-indanone are introduced in portions into 540 ml of fuming nitric acid (d=1.54), cooled to -20° C., so that the temperature of the reaction mixture remains between -10° and -15° C. After the addition has ended, the mixture is subsequently stirred for 45 minutes at -15° to -20° C., the reaction solution is poured onto ice and the precipitate which has separated out is filtered off and washed with water. The crude product of melting point 110°-113° is recrystallized from ethanol, whereby the melting point of the pure 5-chloro-6-nitro-1-indanone rises to 126°-128° C.
