Synthesis

  • A reaction of {{chem2|K+[BrF4O]-}} (potassium tetrafluorooxobromate(V)) with HF.{{cite journal |last1=Gillespie |first1=Ronald J. |last2=Spekkens |first2=Paul H. |title=Bromyl fluoride and bromosyl trifluoride: preparation and chemical and spectroscopic properties |journal=Journal of the Chemical Society, Dalton Transactions |date=1 January 1977 |issue=16 |pages=1539–1546 |doi=10.1039/DT9770001539 |language=en |issn=1364-5447}}
  • Hydrolysis of bromine pentafluoride at low temperatures:

::{{chem2|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,{{cite journal |last1=Seppelt |first1=Konrad |title=Reactions of Bromine Fluoride Dioxide, BrO2F, for the Generation of the Mixed-Valent Bromine Oxygen Cations Br3O4+ and Br3O6+ |journal=Angewandte Chemie International Edition |date=19 December 2019 |volume=58 |issue=52 |pages=18928–18930 |doi=10.1002/anie.201912271 |pmid=31622009 |language=en |issn=1433-7851|pmc=6973041 }} and corrodes glass at room temperature.

Chemical properties

{{uncited section|date=January 2025}}

  • Decomposes when heated:

::{{chem2|3 BrO2F -> BrF3 + Br2 + 3 O2}}

  • Reacts violently with water:

::{{chem2|BrO2F + H2O -> HBrO3 + HF}}

::{{chem2|BrO2F + 2 NaOH -> NaBrO3 + NaF + H2O}}
