Iodobenzene is commercially available, or it can be prepared in the laboratory from aniline via the diazotization reaction. In the first step, the amine functional group is diazotized with hydrochloric acid and sodium nitrite. Potassium iodide is added to the resultant phenyldiazonium chloride, causing nitrogen gas to evolve. The product is ...

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 .
Bromobenzene is an aryl bromide and the simplest of the bromobenzenes, consisting of a benzene ring substituted with one bromine atom. Its chemical formula is C 6 H 5 Br . It is a colourless liquid although older samples can appear yellow.

Phenylmagnesium bromide is prepared by reaction of bromobenzene with magnesium metal. Phenylmagnesium bromide is commercially available as solutions of diethyl ether or THF. Laboratory preparation involves treating bromobenzene with magnesium metal, usually in the form of turnings.
All three have been synthesized by various routes: 1-Bromo-2-chlorobenzene: from 2-chloroaniline, via diazotization followed by a Sandmeyer reaction [1]; 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution [2] [better source needed]
Aryl halides react with metals, generally lithium or magnesium, to give organometallic derivatives that function as sources of aryl anions. By the metal-halogen exchange reaction, aryl halides are converted to aryl lithium compounds. Illustrative is the preparation of phenyllithium from bromobenzene using n-butyllithium (n-BuLi):
