[reaction: see text] A series of phosphonochloridates and phosphonyl dichlorides were prepared, and their reactivity with triethylamine has been investigated using (31)P NMR spectroscopy. Taken together these studies provide evidence that an intramolecular hydrogen-bond is required for phosphonylammonium salt formation to render the phosphorus more electron-deficient.
[反应：见正文] 制备了一系列膦酰氯和磷酰二氯，并使用³¹P核磁共振光谱研究了它们与三乙胺的反应活性。综合这些研究提供了证据，即形成磷酰铵盐需要分子内氢键以使磷更缺电子。
