5‐dinitroimidazoles have been selectively reduced to the corresponding aminonitroimidazole derivatives, using iron dust in glacial acetic acid at room temperature. 2,4‐Dinitroimidazoles have been reduced to the 2‐amino‐4‐nitro‐derivatives only but 4,5‐dinitroimidazoles have given 4‐amino‐5‐nitro‐ or 5‐amino‐4‐nitro‐ derivatives depended on the structure of the N‐substituent.

在室温下,使用冰醋酸中的铁粉将一系列N取代的2,4-二硝基咪唑,4,5-二硝基咪唑和2-甲基-4,5-二硝基咪唑选择性还原为相应的氨基硝基咪唑衍生物。2,4-二硝基咪唑仅被还原为2-氨基-4-硝基衍生物,但是4,5-二硝基咪唑根据结构的不同给出了4-氨基-5-硝基或5-氨基-4-硝基衍生物。的ñ -取代。J.杂环化学。(2010)。
