W. Bocian et al., MULTINUCLEAR NMR-STUDY OF SOME MESOIONIC 3-PHENYL-1-THIA-2,3,4-TRIAZOL-3-IUM-5-YLMETHANIDES WITH VARIOUS EXOCYCLIC GROUPS, Perkin transactions. 2, (7), 1994, pp. 1467-1470
Six mesoionic 3-phenyl-1 -thia-2,3,4-triazol-3-ium-5-ylmethanides (3,5
-9) have been synthesized for the first time. C-13, N-14 and N-15 NMR
data have been collected and interpreted in terms of molecular structu
re. The 1J(C-13-C-13) coupling constants of the ring-exocyclic group b
ond have been determined and are discussed.
