Abstract:
© Pleiades Publishing, Ltd., 2014. Structure and intramolecular transformations of N-phenyl,N'-(diisopropoxythiophosphoryl)thiourea has been studied by NMR spectroscopy and the AM1 quantum-chemical simulation. It has been shown that several forms, including two amide forms (EZ and ZE) and two prototropic forms, coexist in a dynamic equilibrium.
