Description

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.
