Mass and infrared spectroscopy confirmed the structure of the intramolecular condensation product of N-ethyl-N-carboxymethyl-N-ethyldiethylphosphoryliminourea as 1,3-diethyl-2-diethylphosphorylimidohydantoin. The reaction previously observed proceeds on the same pattern for other analogous mixed N,N′-disubstituted phosphorylated iminoureas.
In investigating 1,3-diethyl-2-diethylphosphoryl imidohydantoin, we established that the hydrogen atoms of the methylene group of the imidohydantoin ring are rather mobile in water.
