General description
Bromine is present in gaseous form in lower atmosphere generated by marine activity and as a by product produced from the leaded gasoline combustion. It is widely used as a brominating agent.
Application
Bromine may be used as one of the reactants in the preparation of:
- quinones
- α,β-dibromosuccinic acid
- (Z)-ethyl 2-bromo-5-(trimethylsilyl)pent-2-en-4-ynoate
- α,α′-dibromo-2′,4′-dinitro-2(or3 or 4)-(acetyloxy)bibenzyls
- dibenzylnaphthols
Bromine may be used to catalyze:
- Aziridination of olefins with chloramine-T to form N-tosyl aziridines.
- Conversion of epoxides and CO2 to cyclic carbonates in a continuous flow system.
