The fluoronitramide anion, as its potassium, tetraisopropyl p-phenylenediguanidinium, and tetraphenylphosphonium salts, have been synthesized. The latter salt was characterized in detail as it was by far the most stable. The free acid HN(F)(NO2) was found to be unstable, as was the ammonium salt of fluoronitramide. The fluorine atom was shown to be capable of displacement by nucleophiles. In contrast to dinitramide, which at room temperature is unreactive towards aqueous alkali, fluoronitramide reacts instantly with aqueous hydroxide. Single crystal X-ray diffraction data show an unusual degree of uncertainty in the position of the fluorine atom in all of the salts that were examined.
我们合成了氟硝酰胺阴离子及其钾盐、四异丙基对苯基二胍盐和四苯基鏻盐。对后一种盐进行了详细表征,因为它是迄今为止最稳定的一种盐。游离酸 HN(F)(NO2)不稳定,氟硝胺的铵盐也是如此。事实证明,氟原子能够被亲核物置换。二硝酰胺在室温下对水碱没有反应,而氟硝酰胺却能立即与氢氧化物水溶液发生反应。单晶 X 射线衍射数据显示,在所研究的所有盐类中,氟原子的位置都具有不同寻常的不确定性。
