2,4,5-Trifluorobenzoic Acid is a useful synthetic intermediate. It can be used to synthesize quinolone antibacterial agnts.
Synthesis of 2,4,5-trifluorobenzoic acid: Tetrachloroisophthalonitrile was used as the starting material, which was fluoridated, selectively reduced, and partially defluoridated to obtain 2,4,5-trifluoroisophthalonitrile. This compound was hydrolyzed to form 2,4,5-trifluoroisophthalic acid. Then, selective decarboxylation of 2,4,5-trifluorobenzoic acid was carried out to prepare 2,4,5-trifluorobenzoic acid.
2,4,5-Trifluorobenzoic acid is an important quinolone antibacterial intermediate. It is used in the synthesis of Temafloxacin and liquid crystals, among others.
