Aromatic compounds bearing a basic nitrogen atom can be converted to the corresponding nitric acid salts. Mono-nitration of the compounds can be carried out by adding a dichloromethane solution of the salts to sulfuric acid, or by adding acetyl chloride (or trifluoroacetic anhydride) to a dichloromethane solution of the salts. This protocol provides, among other benefits, the most convenient and reliable
带有碱性氮原子的芳族化合物可以转化为相应的硝酸盐。化合物的单硝化反应可以通过将盐的二氯甲烷溶液添加到硫酸中,或将乙酰氯(或三氟乙酸酐)添加到盐的二氯甲烷溶液中来进行。除其他优点外,该协议还提供了最方便,最可靠的方式来防止硝化过度/欠燃,尤其适用于规模放大。
