Bromyl fluoride

Bromyl fluoride is an inorganic compound of bromine, fluorine, and oxygen with the chemical formula BrO2F.

Synthesis

 * A reaction of K[BrF4O] with HF.


 * Also, reactions of BrF5 with IO2F, IOF3, and I2O5 produce BrO2F.


 * Hydrolysis of bromine pentafluoride at low temperatures:
 * BrF5 + 2H2O -> BrO2F + 4HF

Physical properties
The compound forms a colorless volatile liquid that decomposes at temperatures above 10°C. Corrodes glass at room temperature. Highly reactive and unstable.

Chemical properties

 * Decomposes when heated:
 * 3BrO2F -> BrF3 + Br2 + 3O2


 * Reacts violently with water (with an explosion):
 * BrO2F + H2O -> HBrO3 + HF


 * Reacts with alkalis:
 * BrO2F + 2NaOH -> NaBrO3 + NaF + H2O
