Process for producing α, α, α-trifluoro-o-toluic fluoride

α,α,α-trifluoro-o-toluic fluoride is produced in good yield and high purity by reacting anhydrous hydrogen fluoride with 1,1,3,3-tetrachloro-1,3-dihydroisobenzofuran or a mixture of α,α,α-trichloro-o-toluic chloride therewith, the mixture being preferably produced by sufficiently photochlorinating o-toluic chloride in mild conditions.
