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]Шаблон: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] or phenylphosphorus tetrachloride[5]
