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:
It can also be used as an oxidizing agent for the oxidation of:
It can also be used as a Lewis acid catalyst to:
- 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.
