Versuchsvorschrift

To a solution of 1.50 g (6.75 mmol) of m-bis(trimethylsilyl)benzene in 4.0 ml of acetic anhydride was added dropwise a solution of 1.6 ml (35.6 mmol) of 94% nitric acid in 5 ml of acetic anhydride at 130° C. with stirring. The mixture was stirred for 30 minutes. The reaction mixture was poured into a mixture of ice and 2% potassium carbonate solution and methylene chloride and separated. The aqueaus layer was extracted with methylene chloride. The organic layer was washed successively with water and 2% potassium hydroxide solution, dried and evaporated. The residue was purified by column chromatography on silica gel [eluent: methylene chloride-cyclohexane (1:3-1:5)] to give 475 mg of pale yellow liquid.
