1-Indanone → 4-Nitroindan-1-one

Participants

Reaction Steps

To a 0° C. solution of indanone (1.1 mL, 9.16 mmol, 1.0 equiv) in concentrated H2SO4 (9 mL) was added KNO3 (926 mg, 9.16 mmol, 1.0 equiv) as a solid in several portions over 5 min. After stirring for 1 h, the reaction mixture was poured onto ice. The aqueous suspension was extracted with EtOAC (3×30 mL), and the combined organic layers were washed with brine, dried over sodium sulfate, and concentrated in vacuo. Purification by silica gel chromatography (20%-50% EtOAc/Hexanes) provided the desired compound as a yellow solid (288 mg, 18%).
