Bromine monofluoride is a quite unstable
interhalogen compound with the chemical formula BrF. It can be produced through the reaction of
bromine trifluoride (or
bromine pentafluoride) and
bromine
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest element in group 17 of the periodic table ( halogens) and is a volatile red-brown liquid at room temperature that evaporates readily to form a simi ...
. Due to its lability, the compound can be detected but not isolated:
:BrF
3 + Br
2 → 3 BrF
:BrF
5 + 2 Br
2 → 5 BrF
:Br
2(l) + F
2(g) → 2 BrF
(g)
It is usually generated in the presence of
cesium fluoride
Caesium fluoride or cesium fluoride is an inorganic compound with the formula CsF and it is a hygroscopic white salt. Caesium fluoride can be used in organic synthesis as a source of the fluoride anion. Caesium also has the highest electropositivi ...

Bromine monofluoride decomposes at normal temperature through
dismutation
In chemistry, disproportionation, sometimes called dismutation, is a redox reaction in which one compound of intermediate oxidation state converts to two compounds, one of higher and one of lower oxidation states. More generally, the term can b ...
to bromine trifluoride, bromine pentafluoride, and free bromine.
