Bromosyl trifluoride is an inorganic compound of bromine, fluorine, and oxygen with the chemical formula BrOF₃. ^{[1] [2]}

Synthesis

• Synthesis of bromosyl trifluoride is by reaction of anhydrous HF with K⁺[BrOF₄]⁻ (potassium tetrafluorooxobromate(V)) at –78 °C. ^[3]

HF + K[BrOF₄] → BrOF₃ + K[HF₂]

• Also it can be formed by a reaction of LiNO₃ with BrF₅. ^[4]

Physical properties

Bromosyl trifluoride forms a colorless liquid at room temperature. It reacts with water. ^[5]

Chemical properties

Bromosyl trifluoride is quite unstable and decomposes at room temperature:

2 BrOF₃ → 2 BrF₃ + O₂
