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.

4. Structure and intramolecular mobility of N-(thio)phosphoryl(thio)amides: XV. Study of structure and intramolecular dynamics of N3-phenyl- N1-(diisopropoxythiophosphoryl)thiosemicarbazide in CD2Cl2 solution by 1H, 13C and 31P NMR spectroscopy

Abstract

Structure and intramolecular transformations of N3-phenyl-N1-(diisopropoxythiophosphoryl)-thiosemicarbazide in CD2Cl2 were studied by one- and two-dimensional 1H, 13C and 31P NMR spectroscopy. The combined analysis of the data of NMR spectroscopy and calculation simulation confirmed a high lability of the studied compounds resulting in the formation of various conformational and tautomeric forms in solutions. The preference of Z,E-conformation of the amide form with cis- and trans-location of two N-H groups and the C=S group relatively to the two C-N bonds was revealed. [ABSTRACT FROM AUTHOR]
