実験手順
1,4-Dimethoxyanthraquinone (II) (0.596 g, 2 mmole) is dissolved in hot aceton (60 ml) and argentic oxide (1g, 8mmole) was added to this warm solution. Brief sonication forms a uniform dispersal of oxident. The mixture is heated up to boiling on steam bath again and the mixture stirred vigorously with magnetic stirrer. The oxidation is then initiated by the addition of 6N aqueous nitric acid (2 ml). After addition, the mixture is stirred while cooling for an extra 20 minutes and filtered. The residue is washed thoroughly with water and dried under reduced pressure to give quinizarinquinone (III) as a brown solid.
