Nitric Acid → 5-(2-Fluoro-5-nitrophenyl)-cyclohexane-1,3-dione

Participants

Reaction Steps

60 g of 5-(2-fluorophenyl)-cyclohexane-1,3-dione were dissolved in 500 ml of concentrated sulfuric acid at -20° C. and nitrated with 18.3 g of 98% strength nitric acid at -20° C. in the course of 60 minutes. The reaction mixture was stirred into 5 l of ice water, and the precipitated crystals were filtered off under suction and dried. 60.5 g (83% yield) of 5-(2-fluoro-5-nitrophenyl)-cyclohexane-1,3-dione of melting point 171°-173° C. were obtained.
