Procedure

15 g (68.44 mmol) of 3-pentafluorosulfanylphenylamine was suspended with 10.14 g (68.44 mmol) of phthalic anhydride in 40 ml of a acetic acid and boiled under reflux for 2 h. The cool reaction mixture was admixed with 400 ml of water, heated in an ultrasound bath for 30 min and filtered. The residue was washed with water and subsequently with a little ethanol and dried under reduced pressure. 2-(3-Pentafluorosulfanylphenyl)isoindole-1,3-dione was obtained with a melting point of 188-190° C.
