Bromosyl trifluoride

Bromosyl trifluoride is an inorganic compound of bromine, fluorine, and oxygen with the chemical formula BrOF3.

Synthesis
Synthesis of bromosyl trifluoride is by reaction of anhydrous HF with K[BrOF4] at –78 °C.


 * HF + K[BrOF4] -> BrOF3 + K[HF2]


 * Also it can be formed by a reaction of LiNO3 with BrF5.

Physical properties
Bromosyl trifluoride forms a colorless liquid at room temperature. It reacts with water.

Chemical properties
Bromosyl trifluoride is quite unstable and decomposes at room temperature:


 * 2BrOF3 -> 2BrF3 + O2
