Reaction Conditions:
with trifluoroacetyl peroxide in dichloromethane at -5 - 5; for 1 h;
Steps:
2
Add a peroxytrifluoroacetic acid solution to the reaction vessel, lower the temperature to -5 to 5 ° C, add 381.7g (3.53mol) of p-aminoaniline, keep the temperature at -5 to 5 ° C, and stir the reaction for 1 hour. After the reaction, add 2L of water and stir , The layers were left to stand, and the organic layer was washed with 2L saturated sodium bisulfite solution, 2L saturated sodium bicarbonate solution, and water to pH 7-8, and the solvent was distilled off under reduced pressure. Dichloromethane and methanol (dichloromethane and The volume ratio of methanol was 1: 2) The solution was recrystallized to obtain 456.9 g (yield 77%) of the product as a yellow solid p-nitronitrobenzene
