Abstract

^13^C and ^15^N NMR chemical shifts are reported for 2,3‐diphenyltetrazolium‐5‐olate and ‐5‐thiolate and some of their derivatives. The data for N‐1 and C‐5 provide a very satisfactory means of distinguishing between O and S as the exocyclic substituent. The reported chemical shifts are consistent with the presence of the cyclic structures shown, rather than of the corresponding non‐cyclic structures.

## Abstract ^13^C, ^14^N and ^15^N NMR data are reported for some mesoionic 2,3‐diphenyltetrazoles with nitrogen‐containing exocyclic groups, and the data confirm their cyclic structures. The protonated forms of these mesoionic structures contain hydrogen atoms at the exocyclic groups.

The 15N NMR spectra of the novel seven-membered 1,2,3,5-tetrazepinone ring systems were studied. The chemical shift of N-2 was found to be signiÐcantly responsive to substituent changes at the phenyl ring. As the electron-withdrawing character of the substituents increased, N-2 became more deshielde
