4-Fluorobromobenzene is synthesized via bromination of fluorobenzene in the presence of a Lewis acid catalyst such as iron(III) bromide or aluminium tribromide. [2]4-Bromofluorobenzene is regarded by the Toxic Substances Control Act as a high production volume chemical, that is, a chemical that 1 million pounds (about 500 tonnes) per year is either produced in or imported to the United States.
In contrast, the boiling points of PhF and benzene are very similar, differing by only 4 °C. It is considerably more polar than benzene, with a dielectric constant of 5.42 compared to 2.28 for benzene at 298 K. [4] Fluorobenzene is a relatively inert compound reflecting the strength of the C–F bond.
A series of studies have shown that bromophenols derived from brominated flame retardants (BFRs) in human environments are present in human blood and breast milk. [1] Bromophenols (as well as PBDEs) were detected in 88% of samples, with 2,4,6-Tribromophenol present in 84% of breast milk samples alone.
This reagent can be used, e.g. in the reaction with carbon dioxide to prepare benzoic acid. [4] Other methods involve palladium-catalyzed coupling reactions , such as the Suzuki reaction . Bromobenzene is used as a precursor in the manufacture of phencyclidine .
