    en.wikipedia.org/wiki/1-Bromo-4-fluorobenzene

    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.

    Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.

    It may be prepared via the Schiemann reaction, in which a 4-aminobenzoic acid, protected as the ethyl ester, is diazotised and then fluoride introduced using tetrafluoroborate. Hydrolysis of the ester converts it back to the free acid. [2] 4-Fluorobenzoic acid has been observed to form by the aerobic biotransformation of 4-fluorocinnamic acid. [3]
