The Uses of 1-Bromo-2-nitrobenzene

1-Bromo-2-nitrobenzene may be used in the preparation of:

4-methoxy-2′-nitrodiphenyl ether
1-methoxy-3,5-bis-(2-nitro-phenoxy)benzene
5-hydroxy-3-methoxy-2′-nitrodiphenyl ether

General Description

1-Bromo-2-nitrobenzene undergoes palladium[0]-mediated Ullmann cross-coupling reaction with a range of β-halo-enals, -enones or -esters to afford the corresponding β-aryl derivatives. Palladium[0]-mediated Ullmann cross-coupling reaction of 1-bromo-2-nitrobenzene with β-bromo-α,β-unsaturated aldehydes is reported.

Purification Methods

Crystallise it twice from pet ether, using charcoal before the first crystallisation. [Beilstein 5 III 618, 5 IV 728.]
