Bromochlorobenzene

Bromochlorobenzenes are mixed aryl halides (aryl chloride and aryl bromide) consisting bromine and chlorine as substituents on a benzene ring.

All three have been synthesized by various routes:

• 1-Bromo-2-chlorobenzene: from 2-chloroaniline, via diazotization followed by a Sandmeyer reaction
• 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution
• 1-Bromo-4-chlorobenzene:
• From a derivative of (4-bromophenyl)silane using N-bromosuccinimide
• From 4-chlorophenol using triphenylphosphine dibromide or phenylphosphorus tetrachloride
