The usefulness of 13 C nmr spectroscopy in the tautomeric assignment of 5‐(monosubstituted)‐amino‐1,2,3,4‐thiatriazoles is demonstrated. The reaction products, derived therefrom by alkylation, acylation and sulfonylation, are also readily characterized by an inspection of the 13 C 5 signal shift. For thiatriazolinethione, the 13 C nmr spectrum indicates the presence of a thioketone function ( 6 , δ 193.1 ppm) instead of a thiol function (7).
