Latest Patents

Kodaira's latest patents include a process for producing .alpha., .alpha., .alpha.-trifluoro-o-toluic fluoride. This compound 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 .alpha., .alpha., .alpha.-trichloro-o-toluic chloride. The mixture is preferably produced by sufficiently photochlorinating o-toluic chloride under mild conditions. Another significant patent involves the process for producing 1,1,3,3-tetrafluoro-1,3-dihydro-isobenzofuran. This compound 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 serve as an intermediate in the preparation of a fungicidal compound.
