Application
Bromine can be used as an oxidizing agent for the oxidation of:
Bromine can also be used along with other co-reactants such as hexamethylphosphoric triamide (HMPA) and bis(tributyltin) oxide (HBD) to selectively oxidize secondary alcohols. However, bromine/nickel carboxylates convert 1,4-diols to γ-butyrolactones by selective oxidation of the primary alcohols.
- Primary alcohols to either aldehydes or esters and secondary alcohols to give ketones.
- Alcohols or diols to tetrahydrofurans in the presence of silver(I) salts.
- Enediol bis-trimethylsilyl ethers to α-diketones.
- Aldehydes to esters in the presence of alcohol solvents and sodium bicarbonate buffer.
- Aliphatic and aromatic thiols to disulfides.
