ABSTRACT:
1,1,3,3-Tetrafluoro-1,3-dihydro-isobenzofuran is produced easily in good yield and high purity by allowing .alpha.,.alpha.,.alpha.-trichloro-o-toluic chloride to react with anhydrous hydrogen fluoride at an amount ratio of 4 moles or slight excess of the latter to 1 mole of the former. The final product may be used as an intermediate in the preparation of a fungicidal compound.
