Bromyl fluoride is an inorganic compound of bromine, fluorine, and oxygen with the chemical formula BrO2F.[1][2]
Synthesis
- A reaction of K[BrF4O] with HF.[3]
- Also, reactions of BrF5 with IO2F, IOF3, and I2O5 produce BrO2F.[3]
- Hydrolysis of bromine pentafluoride at low temperatures:
- BrF5 + 2 H2O → BrO2F + 4 HF
Physical properties
The compound forms a colorless volatile liquid that decomposes at temperatures above 10 °C. It is highly reactive and unstable,[4] and corrodes glass at room temperature.
Chemical properties
- Decomposes when heated:
- 3 BrO2F → BrF3 + Br2 + 3 O2
- Reacts violently with water:
- BrO2F + H2O → HBrO3 + HF
- Reacts with alkalis:
- BrO2F + 2 NaOH → NaBrO3 + NaF + H2O
