Bromine(I) fluorosulfonate is an inorganic compound of bromine, sulfur, fluorine, and oxygen with the chemical formula . 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:
The reduction of bromine(III) fluorosulfonate also yields bromine(I) fluorosulfonate:
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:
