Perbromyl fluoride is an inorganic compound of bromine, fluorine, and oxygen with the chemical formula BrO₃F.^[1]

Synthesis

Synthesis of perbromyl fluoride is by the effect of antimony pentafluoride on a solution of potassium perbromate in hydrofluoric acid:^[2]

KBrO₄ + 2 SbF₅ + 3 HF → BrO₃F + K[SbF₆] + H[SbF₆]·H₂O

Physical properties

Perbromyl fluoride is a colorless gas at room temperature that is stable in the absence of moisture.^[3]

Chemical properties

Perbromyl fluoride reacts with water to produce perbromic acid and hydrogen fluoride:

BrO₃F + H₂O → HBrO₄ + HF
