Abstract

Phosphorylotropic rearrangement in N,N′-(bis)(diizopropoxyphosphorylamidocarbonyl)-1,10-diaza-18-crown-6-ester dissolved in DMSO was investigated by 1H, 13C, and 31P NMR spectroscopy. The transition from the amide form to the phosphorylotropic form was shown to cause a simultaneous signal modification of the NMR spectra of three mentioned isotopes in all structural elements of the molecule.
