Reaction Conditions

Reaction Steps

To a solution of 1.18 g (4.00 mmol) of sym-tris(trimethylsilyl)benzene in 1.7 ml of acetic anhydride was added a solution of 0.4 ml (9.1 mmol) of 94% nitric acid in 1.7 ml of acetic anhydride at -10° C. The mixture was stirred at 10 to -5° C. for 2 hours and then at room temperature for 22 hours. The reaction mixture was poured into sodium hydroxide solution and the aqueous solution was extracted with methylene chloride. The extract was evaporated. The residue was purified by column chromatography on silica gel [eluent: petroleum ether] to give 636 mg of pale yellow crystals, m.p.86°-87° C. (yield 59%).
