1H-Indene-1,3(2H)-dione, 5,6-dimethyl-

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 5,6-dimethyl indane-1,3-dione (0.52 g; 0.003 mole) suspended in anhydrous ether (5 ml.) was stirred at 10°C during the dropwise addition of fuming nitric acid (1.0 ml.). After the addition was complete the mixture was stirred at ambient temperature for 1 hr. and the precipitated yellow solid filtered. m.p. (water, hydrochloric acid) 111°-113°C. (Found: C, 60.11; H, 4.10; N, 6.14; C11H9NO4 requires: C, 60.28; H, 4.14; N, 6.39%). After the addition and the precipitated yellow solid filtered m.p. (water, hydrochloric acid) 111°-113°C. (Found: C, 60.11; H, 4.10; N, 6.14; C11H9NO4 requires: C, 60.28; H, 4.14; N, 6.39%)
