1,2-Dibromo-4,5-difluoro-3-nitrobenzene Use and Manufacturing
First, 8 mL of 30percent by mass fuming sulfuric acid was cooled to 5°C, and 1.45 g of 65percent nitric acid (equivalent to 15 mmol of nitric acid) was then added gradually. Following completion of the addition, the temperature was raised to room temperature, and after stirring for 5 minutes, 2.71 g (10 mmol) of 1, 2-dibromo-4, 5-difluorobenzene was added. The temperature of the reaction mixture was raised to 35°C, the mixture was stirred for 1 hour 30 minutes, and the temperature was then cooled to room temperature. The reaction mixture was poured onto ice, and the product was extracted with ethyl acetate. The resulting ethyl acetate solution was washed twice with water, and then with a saturated aqueous solution of sodium bicarbonate and a saturated saline solution, before being dried over magnesium sulfate. The magnesium sulfate was then removed by filtration, and quantitative analysis of the resulting solution by HPLC revealed a reaction yield of 94percent of the target product 1, 2-dibromo-4, 5-difluoro-3-nitrobenzene.
