In the invented process for producing a nitro compound, an organic substrate and nitrogen dioxide are reacted in the presence of oxygen or are reacted in a molar ratio of nitrogen dioxide to the organic substrate of less than 1 to yield a corresponding nitro compound. The reaction may be performed in the presence of N-hydroxyphthalimide or other imide compounds. Such organic substrates include (a) aliphatic hydrocarbons, (b) alicyclic hydrocarbons, (c) non-aromatic heterocyclic compounds each having a carbon atom on a ring, which carbon atom is bonded to a hydrogen atom, (d) compounds each having a carbon-hydrogen bond at the adjacent position to an aromatic ring, and (e) compounds each having a carbon-hydrogen bond at the adjacent position to a carbonyl group. This process can efficiently nitrate an organic substrate even under relatively mild conditions.
在制备硝基化合物的发明过程中,有机底物和二氧化氮在氧气存在下反应,或者在二氧化氮与有机底物的摩尔比小于1的情况下反应,以产生相应的硝基化合物。该反应可以在N-羟基邻苯二甲酰亚胺或其他亚酰胺化合物存在下进行。这样的有机底物包括(a) 脂肪烃,(b) 脂环烃,(c) 非芳香杂环化合物,每个环上的碳原子与氢原子相结合,(d) 每个化合物在芳香环旁边位置具有碳氢键,以及(e) 每个化合物在酮基旁边位置具有碳氢键。这个过程可以在相对温和的条件下有效地对有机底物进行硝化。
