Notes:
The natural abundance 15N NMR spectra of sulphamide, sixteen 1,2,6-thiadiazine and two 1,2,4,6-thiatriazine derivatives, phenylbutazone and antipyrine have been recorded for the first time. The influence of substituents on nitrogen chemical shifts and the effect of intercalation of SO2 and CO groups between two nitrogen atoms are discussed. Prototropic tautomerism was also studied. 13C NMR data for some of the 1,2,6-thiadiazine and thiatriazine derivatives are reported.
