Bromochlorobenzene

Bromochlorobenzenes are mixed aryl halides (aryl chloride and aryl bromide) consisting bromine and chlorineassubstituents 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]
• 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution^{[2][better source needed]}
• 1-Bromo-4-chlorobenzene:
  • From a derivative of (4-bromophenyl)silane using N-bromosuccinimide^[3]
  • From 4-chlorophenol using triphenylphosphine dibromide^[4]orphenylphosphorus tetrachloride^[5]
