SYNTHESIS AND CHARACTERIZATION OF MESOIONIC 1,3,4-TRIAZOLIUM-2-SELENOLATES
摘要:
A new improved synthesis of mesoionic 1,3,4-triazolium-2-selenolates is described and three new members of the series thus obtained. They were characterized by Elemental Analysis, I.R., H-1 and C-13 NMR and Mass Spectra. The data obtained have been discussed. The chemical shifts at C-2 in the negative region and at C-5 in the positive region were compared with data for corresponding mesoionic-2-thiolates. Our data were also compared with available data for some related classes of mesoionic compounds.
