Nitric Acid → 4-Methyl-2-nitroindane-1,3-dione

Participants

Reaction Steps

To a stirred suspension of 4-methyl-1,3-indane-dione (1.02 g. 0.006 mole) in anhydrous ether (5 ml) at ca 10°C was added dropwise and with stirring fuming nitric acid (2.0 ml). After 10 mins. a clear, dark solution formed followed by precipitation of a bright yellow N The mass was filtered and washed with 5N. hydrochloric acid. Recrystallization from water/hydrochloric acid afforded the title compound, m.p. 108°-9°C. (Found; C, 56.16; H, 3.74; N, 6.32; C10H7NO4.1 /2H2O requires; C, 56.07; H, 3.76; N, 6.54%).
