N-methylurotropinium or methylhexaminium) fluoride was prepared by either halogen exchange between the corresponding iodide and AgF or by a single-step, one-pot, self-assembling synthesis from aqueous CH3NH2, HF, formaldehyde, and NH3. It was characterized by NMR and vibrational spectroscopy. Its hydrate undergoes at 70 °C a Sommelet-type ring opening and coupling reaction to form a potential cryptand system
无水 1-甲基六亚甲基四胺(也称为 N-甲基六亚甲基四胺)氟化物通过相应的碘化物和 AgF 之间的卤素交换或通过一步、一锅、自组装合成从 CH3NH2、HF、甲醛水溶液制备, 和 NH3。通过核磁共振和振动光谱对其进行表征。它的水合物在 70 °C 下发生 Sommelet 型开环和偶联反应,形成潜在的穴状配体系统,该系统由两个双环三嗪基团组成,这些基团通过亚甲基桥连接并含有八个三元氮原子。该化合物通过多核核磁共振和振动光谱表征,其结构由单晶 X 射线衍射数据确定。
