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.
The Wohl–Ziegler reaction [1] [2] is a chemical reaction that involves the allylic or benzylic bromination of hydrocarbons using an N-bromosuccinimide and a radical initiator. [3] Best yields are achieved with N-bromosuccinimide in carbon tetrachloride solvent. Several reviews have been published. [4] [5]
Bromobenzene is an aryl bromide and the simplest of the bromobenzenes, consisting of a benzene ring substituted with one bromine atom. Its chemical formula is C 6 H 5 Br. It is a colourless liquid although older samples can appear yellow. It is a reagent in organic synthesis.

Chemical structure of 2-bromophenol. A bromophenol is an organic compound consisting of hydroxyl groups and bromine atoms bonded to a benzene ring. They may be viewed as hydroxyl derivatives of bromobenzene, or as brominated derivatives of phenol. There are five basic types of bromophenols (mono- to pentabromophenol) and 19 different ...

Trifluoromethyl group covalently bonded to an R group. The trifluoromethyl group is a functional group that has the formula-CF 3. The naming of is group is derived from the methyl group (which has the formula -CH 3), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane H– CF 3, 1,1,1-trifluoroethane H ...
