This paper uses the examples of N/sup 1//sub 2/, N/sup 2/-dialkyl-N/sup 2/-bis (o-phenylenedioxa) phosphoranylamidines (IA-VA) and N/sup 1/, N/sup 2/-dialkylamidinium-bis (o-phenylenedioxa) phosphorates (IB-VB) to investigate the process of 1,3 migration of the phosphoranyl groups, as well as permutational isomerizations in the tetragonal bypyramid of hexacoordinated phosphorus. The temperature dependence of the signals of the methyl protons of the isopropyl groups in the H 1 NMR spectra of a tautomeric mixture are shown.
