Bromine monofluoride
Bromine monofluoride is a quite unstable interhalogen compound with the chemical formula BrF. It can be produced through the reaction of bromine trifluoride and bromine. Due to its lability, the compound can be detected but not isolated:
It is usually generated in the presence of cesium fluoride.
Bromine monofluoride decomposes at normal temperature through dismutation to bromine trifluoride, bromine pentafluoride, and free bromine.
