Reaction Steps
DE-A 38 10 093 describes the preparation of tetrafluorobenzoyl chloride by decarboxylation of tetrafluorophthalic acid which is dissolved in an excess of quinoline. After the reaction is completed, a quinoline salt of tetrafluorobenzoic acid is obtained, which is then suspended in thionyl chloride and reacted with heating. The 2,3,4,5-tetrafluorobenzoyl chloride is then obtained by fractional distillation (cf. also Example 4).
