Application

Bromine can be used as a brominating and oxidizing agent in chemical synthesis.It can be used: To brominate alkylbenzenes at the benzylic position using photocatalytic conditions. To prepare brominated aromatic compounds by electrophilic aromatic substitution reactions in the presence of Lewis acid catalysts.For the bromination of carbonyl compounds at a carbonyl group via Hell-Volhard-Zelinski reaction in the presence of phosphorus trihalides.To prepare isocyanates, carbamates, or amines by reacting with primary amides in the presence of base via Hofmann rearrangement.
