Structure and intramolecular mobility of N-(thio)phosphoryl(thio)carbonylamides: X.1 1H, 13C, and 31P NMR study of the structure of N,N'-bis(thio)phosphoryl(thio)urea containing open-chain fragment

Abstract

N,N'-Bis(W-diisopropoxythiophosphorylaminothiocarbonyl)-1,7-diaminoheptane in 3-10% solutions in acetone-d6 exhibits high molecular mobility with realization of two conformations of its molecule, amide-amide proton exchange, and various tautomeric forms.
