Abstract
Se-77, N-15, N-14, C-13 and H-1 NMR data are reported for a series of mesoionic 1,3,4-triazoles with selenium-containing exocyclic groups. T he results obtained show that the molecules studied exist in the cycli c mesoionic structures. The value of 1J(Se-77-C-13) coupling constants show a large amount of double-bond character between the ring C-5 and exocyclic selenium atoms.
