Nitric Acid → 7-Nitro-1-tetralone

Participants

Reaction Conditions

Reaction Steps

5 g of alpha-tetralone are added to 18.2 ml of sulfuric acid cooled to 0° C., while maintaining the temperature <10° C. A mixture of 1.87 ml of nitric acid at 70% in water and of 3.65 ml of sulfuric acid is added while maintaining the temperature <10° C. The reaction medium is stirred for 30 minutes at a temperature <10° C. and then stirred for one hour at ambient temperature. The reaction medium is poured into ice-cold water (250 ml). The insoluble material is filtered off under vacuum and dried, so as to give 5.2 g of 7-nitro-3,4-dihydronaphthalen-1(2H)-one in the form of a beige solid.
