Studies on Organic Sulfur Compounds. XIV. The Reaction of N-Alkoxy-carbonyl-N'-(2-thiazolyl) thioureas with Some Oxidants
1973
N-Alkoxycarbonyl-N'-(2-thiazolyl) thioureas were reacted with some oxidants, such as bromine, benzoyl peroxide, hypobromous acid and N-bromosuccinimide, to afford 2-alkoxycarbonylimino-thiazolo [3, 2-b] thiadiazolines (X). Furthermore, from the reaction mixtures of N-ethoxycarbonyl-N'-(2-thiazolyl) thiourea (12) with bromine in chloroform, N-ethoxycarbonylimino-thiazolo [3, 2-b] thiadiazoline hydrobromide monohydrate (14) was obtained, which was easily dehydrobrominated to form 2-ethoxycarbonylimino-thiazolo-[3, 2-b] thiadiazoline (13) by treatment with large quantities of water. This paper describes particularly in detail about the structures of 13 and 14.
