title: Intramolecular hydrogen-bond participation in phosphonylammonium salt formation.
abstract: [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.
