| abstract | PCT No. PCT/GB93/01112 Sec. 371 Date Dec. 15, 1994 Sec. 102(e) Date Dec. 15, 1994 PCT Filed May 27, 1993 PCT Pub. No. WO94/00407 PCT Pub. Date Jan. 6, 1994.Fluro-substituted aromatic carboxylic acids, and particular 2- and 4-fluorobenzoic acid can be made from the corresponding fluoro-methyl compound such as fluorotoluene in a single stage by the reaction at elevated temperature, preferably of at least 80 DEG C. with hydrogen peroxide and bromide in mole ratios to the substrate of greater than 2:1, and preferably around 3:1, in the presence of means capable of generating bromine free radicals from bromine molecules, such as radiation having a wavelength of not greater than 600 nm or an organic peroxide. |
