Bromine(I) fluorosulfonate is an inorganic compound of bromine, sulfur, fluorine, and oxygen with the chemical formula BrSO3F. This is a monovalent compound of bromine from the group of fluorosulfonates.
Synthesis
Similarly with other halogenofluorosulfonates, the reaction of bromine with peroxydisulfuryl difluoride produces the compound:[2][3]
- Br2 + S2O6F2 → 2BrSO3F
The reduction of bromine(III) fluorosulfonate also yields bromine(I) fluorosulfonate:[4]
- Br(SO3F)3 + Br2 → 3BrSO3F
Chemical properties
Bromo(I) fluorosulfonate is a blackish-red, viscous, hydrolysis-sensitive liquid that reacts violently with water. Upon cooling, it solidifies into a glassy state.
Bromo(I) fluorosulfonate reacts with iodine(I) fluorosulfonate at temperatures above 50 °C to form dibromoiodofluorosulfonate:[5]
- 2BrSO3F + ISO3F → IBr2(SO3F)3
