SYNTHESIS AND CHARACTERIZATION OF MESOIONIC 1,3,4-TRIAZOLIUM-2-SELENOLATES

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., 1Hand 13C 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.
