Versuchsvorschrift

3-Iodophthalic acid (4.00 g, 13.7 mmol) was dissolved in anhydrous acetic acid, and the solution was stirred at 145° C. for 1 hour. The solvent of the reaction mixture was evaporated under reduced pressure and the residue was purified by slurry using diisopropylether to obtain 3-iodophthalic acid anhydride (3.6 g, yield 96%).

Aufarbeitung
