Vorschrift

4,5-difluorophthalic anhydride (0.5 grams, 2.7 mmole) was added to a slurry of cupric oxide (5% by weight of starting material) in 5 ml. of N-methyl-2-pyrrolidone. n-tridecane (0.25 grams) was added as an internal standard. The mixture was heated to 190° C. for 3 hours, at which time GC analysis indicated complete consumption of the starting material and conversion to 3,4-difluorobenzoic acid in an 85% yield, based upon the internal standard, corrected for response factors.
