    en.wikipedia.org/wiki/4-bromobenzaldehyde

    4-Bromobenzaldehyde may be prepared in the laboratory in two steps by oxidation 4-bromotoluene. [4] In the first step, two bromine atoms are added to the methyl group of 4-bromotoluene by free radical bromination to form 4-bromobenzal bromide.

    en.wikipedia.org/wiki/N-Bromosuccinimide

    NBS is commercially available. It can also be synthesized in the laboratory. To do so, sodium hydroxide and bromine are added to an ice-water solution of succinimide. The NBS product precipitates and can be collected by filtration. [1] Crude NBS gives better yield in the Wohl–Ziegler reaction. In other cases, impure NBS (slightly yellow in ...

    en.wikipedia.org/wiki/4-Bromophenylacetic_acid

    4-Bromophenylacetic acid may be prepared by the addition of a bromine atom to phenylacetic acid through electrophilic aromatic substitution.It was first prepared in the laboratory by treatment of phenylacetic acid with bromine and mercuric oxide; a mixture of the 2- and 4- isomers is made, and the 4- isomer is isolated by fractional crystallization.
