Bromine(III) fluorosulfonate is an inorganic compound of bromine, sulfur, fluorine, and oxygen with the chemical formula Br(SO3F)3. This is a trivalent compound of bromine from the group of fluorosulfonates.
Synthesis
The compound is formed as a reaction product of bromine and peroxydisulfuryl difluoride:[1][2]
- Br2 + 3S2O6F2 ⟶ 2Br(SO3F)3
Chemical properties
Bromine(III) fluorosulfonate is very hygroscopic and reacts exothermically with water:[1][2]
- 4Br(SO3F)3 + 6H2O ⟶ 2Br2 + 3O2 + 12HSO3F
The monovalent bromine(I) fluorosulfonate can be formed by adding bromine to bromine(III) fluorosulfonate:[3]
- Br(SO3F)3 + Br2 → 3 BrSO3F
