Participants

Reaction Conditions

Reaction Steps

1,3-Dinitrobenzene (25 g, 149 mmol) was dissolved in sulfuric acid (44.5 mL, 835 mmol) and NBS (31.8 g, 178 mmol) was added. The mixture was stirred at 60° C. for 2 days. The reaction was cooled to ambient temperature and the mixture was poured into ice water to form a precipitate. The product was collected by filtration, washed with water and hexanes to yield 35.1 g (142 mmol, 96%) of 1-bromo-3,5-dinitrobenzene as a beige solid.
