Conclusions
Tosyl azide reacts with 2-acetyl-3-methoxy-5-methyldiazaphospholine to give an iminodiazaphospholine that is stable as a solid, while in solutions, depending on the nature of the solvent and the temperature, it changes to the tautomer with an NH bond and the dimer. The equilibrium interconversion of these three forms was shown on the basis of the IR and31P NMR spectra.
