Replacement of hydrogen by halogen in aromatic nitro compounds

Replacement of hydrogen by halogen in aromatic nitro compounds [Pg.184]

The Waters procedure (see page 151) has proved its value also for preparation of iii-bromonitrobenzene 374 [Pg.184]

Ag2S04 (0.1 mole) is added to nitrobenzene (0.1 mole) and Br2 (0.1 mole) in concentrated H2S04 (90 ml) and water (10 ml), and the whole is shaken at room temperature for 16 h. [Pg.184]

Filtration from AgBr, dilution with water, and extraction with ether give the w-bromo compound, m.p. 55-56°, in 70% yield. [Pg.185]

2-Bromo-4-nitrocumene, inter alia, is obtained similarly.617 The classical bromination of nitrobenzene by bromine and iron powder is recorded in detail in Organic Syntheses.618 [Pg.185]
