General description

Hydrobromic acid is a strong acid that can be used as a brominating reagent for the electrophilic and radical bromination of olefins, alkynes, and ketones.

Application

Hydrobromic acid can be used as a brominating agent:
  • For the regioselective bromination of anilides to bromoanilides.
  • Oxidative bromination of olefins, alkynes, and ketones to corresponding dibrominated alkanes, dibrominated alkenes, and α-bromoketones.
It can also be used as a catalyst for the aerobic photooxidation of alcohols to corresponding carboxylic acids.
