Versuchsvorschrift

A solution of suberic acid (5.0 g, 28.7 mmol) in acetic anhydride (10 mL) was heated at reflux for 1 h. After cooling to RT, the solvent was removed in vacuo. The pale yellow residue was recrystallized from acetonitrile. After filtration and drying to the vacuum pump, the oxonane-2,9-dione was obtained as a white solid (2.26 g, 50.4% yield).
