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