title: NMR investigation of chlorophosphorylation products of N-vinylazoles.
abstract: The structure of novel phosphorus-containing N-vinylazoles prepared by action of phosphorus pentachloride has been studied by multinuclear (1)H, (13)C, (15)N, (31)P and two-dimensional (2D) NMR spectroscopy. N-vinyl-substituted 1,2-diazoles and 1,2,3-triazoles have undergone phosphorylation, exclusively, on double bond. N-vinylazoles-based hexa-coordinated phosphorus compounds have been synthesized for the first time. (31)P NMR spectroscopy provides the most convenient and unambiguous method for the investigation of E-Z-isomeric structures of phosphorylated enamines.
