일반 설명

Bromine is a highly volatile and reactive halogen that can be used as a powerful brominating and oxidizing agent in chemical synthesis.

애플리케이션

Bromine can be used as a brominating agent for the bromination of:
  • Aromatic and heterocyclic compounds. 
  • Carbonyl compounds at α position to carbonyl groups.
  • Aromatic carboxylic acids via Hell-Volhard-Zelinski reaction in the presence of phosphorus trihalides.
  • Alkylbenzenes at the benzylic position using photocatalytic conditions.

It can also be used as an oxidizing agent for the oxidation of:
  • Primary alcohols to either aldehydes or esters.      
  • Secondary alcohols to ketones.

It can also be used as a Lewis acid catalyst to:     
  • Convert epoxides and CO2 to cyclic carbonates in a continuous flow system.     
  • Synthesize bis(indolyl)methanes by reacting indoles with carbonyl compounds.
