Acetic Acid → HCID 11345909, compound

Participants

Reaction Steps

To a suspension of 3,3′-dinitro-4,4′-azofurazan (1.42 g, 6.0 mmol) and Zn (0.78 g, 12 mmol) in 10 ml of methanol at room temperature, was added dropwise glacial acetic acid (0.8 ml, 12 mmol). A vigorous reaction took place, and after the greenish reaction mixture was stirred at room temperature for 2 hours. The slurry was filtered through a bed of celite and the filtrate was concentrated on a rotary evaporator and passed through a bed of silica gel using CH2Cl2/EtOAc. Removal of solvent gave 1.46 g (100% yield, one spot by TLC) of 3,3′-dinitro-4,4′-hydrazofurazan, a pale yellow solid, 1H NMR(DMSO-d6); δ9.98 (s) ppm. Recrystallization from chloroform/acetone gave 1.26 g of 3,3′-dinitro-4,4′-hydrazofurazan, mp 171-173° C.
