Interaction of 2,5-dithio-1,3,4-thiadiazolidine with amines was written by Konher, M. V.. And the article was included in Indian Journal of Chemistry in 1973.Application of 1843-21-6 This article mentions the following:
Treatment of 2,5-dithio-1,3,4-thiadiazolidine with aromatic primary amines at 180-5° gave 3,5-dithio-4-aryl-1,2,4-triazolidine, 2,5-diarylimino-1,- 3,4-thiadiazolidine, 3-thio-4-aryl-5-arylimino-1,2,4-triazolidine, 3- mercapto-1,2,4-triazolo[3,4-b]benzothiazole, and 2-arylaminobenzothia- zole in significant quantities. Mechanism of the reaction was discussed and possible intermediates located. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Application of 1843-21-6).
N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. Thiazole is a five-membered, unsaturated, planar, π-excessive heteroaromatic containing one sulfur atom and one pyridine-type nitrogen atom at position 3 of the cyclic ring system. The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Application of 1843-21-6
