4-Bromoaniline is a compound where an aniline molecule is substituted with a bromine atom on the para position. Commercially available, this compound may be used as a building block, e.g. in the preparation of monobrominated biphenyl via the Gomberg-Bachmann reaction.[2]

Preparation

[edit]

4-Bromoaniline can be made by reacting acetyl chloride-protected aniline with bromine.

Synthesized and purified p-bromoaniline

Reactions

[edit]

One laboratory route to 1-bromo-4-iodobenzene involves the Sandmeyer reaction. 4-Bromoaniline is treated with concentrated sulfuric acid and sodium nitrite, then potassium iodide.[3]
