Jensen, K. A. published the artcileReaction between 5-amino-1,2,3,4-thiatriazole and hydrochloric acid, Name: Formamidine disulfide dihydrochloride, the publication is Acta Chemica Scandinavica (1964), 18(2), 570-2, database is CAplus.
The treatment of monoalkylthioureas with Cl or heating 5-alkylamino-1,2,3,4-thiatriazoles with concentrated HCl 1 hr. at 100° produced derivatives of [RNHC(:NH)S]2 (I). For example, a cooled saturated solution of NH2CSNH2(II) in absolute EtOH treated with Cl gas until the solution yellowed, the mixture filtered, the precipitate dissolved in H2O, and the solution poured into concentrated HCl gave I.2HCl (R = H) (III), m. 172-4° (the substance was diamagnetic). III obtained from II and from 5-amino-1,2,3,4-thiatriazole (IV) were identical, and this result confirmed earlier conclusions (Sahasrabudhey, CA 45, 8006f). III could be produced from IV via reduction of H2NC(:NH)S+ with HN3, both pos. ion and acid being formed by hydrolysis of the thiatriazole ring. I (R = Me).2HCl, m. 163-5°, and I (R = Pr).2HCl, m. 155-6°, were also prepared by both methods. l oxidation of tert-BuNHCSNH2 (V), m. 181°, and the HCl hydrolysis of 5-tert-butylamino-1,2,3,4-thiatriazole produced III. I (R = tert-Bu).2HBr, m. 141-2°, was prepared by the oxidation of V in AcOH with Br in CCl4.
