2,4-DIFLUORO-5-NITROBENZONITRILE Use and Manufacturing
Potassium nitrate (16.4 g, 147.4 mmol) was added to concentrated HPotassium nitrate (16.4 g, 147.4 mmol) was added to concentrated H2S04 (85 ml, 1582 mmol) at 0 °C, followed by slow addition of 2, 4-difluorobenzonitrile (11.0 g, 79.1 mmol). The suspension was stirred at this temperature for an additional 4 hrs and quenched ice/ water (800 ml). The resulting solid was collected by filtration and dried to give the title compound (13.8 g, 95percent) as a white solid. NMR (400 MHz, CDC13) 8.48 (m, 1H), 7.24 (m, 1H).In 251 ^ three bottles, 2, 4-difluorobenzonitrile (17.28, 123.71111111) dissolved in concentrated sulfuric acid (351 ^), coolingTo -10 ° C, dropping fuming nitric acid (155.9g, 2474.4mmol), incubation reaction 0.5h, room temperature reaction lh. The reaction is finished, The liquid slowly into the ice that is solid precipitation, filtration, filter cake vacuum drying 2, 4 - difluoro - 5 - nitrobenzonitrile 20. lg, yieldWas 88.4percent.[0207] To a solution of
