Synthesis

Synthesis of bromosyl trifluoride is by reaction of anhydrous HF with K[BrOF4] at –78 °C.[3]

HF + K[BrOF4] → BrOF3 + K[HF2]

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:

2BrOF3 → 2BrF3 + O2
