Abstract: A process for the preparation of 5-fluoro-2-phenyl-4H-3,1-benzoxazin-4-ones of the formula (I) in which R denotes hydrogen, halogen, C1- to C3-alkyl, m- or p- trifluoromethyl, trifluoromethoxy, chlorodifluoromethoxy, difluoromethoxy, tetrafluoroethoxy, trifluoromethylmercapto or chlorodifluoromethylmercapto, by reaction of appropriate 2-phenyl-4H-3,1-benzoxazin-4-ones, in particular 5-chloro- or 5-bromo-substituted 2-phenyl-4H-3,1-benzoxazin-4-ones (II) with alkali metal fluoride in the presence of a solvent, the reaction being carried out with the exclusion of water, according to patent ... (Patent Application P 3335456.1), in which, in a further embodiment, the process according to the main claim is carried out in the presence of a metal iodide and/or of iodine.
