Studies on Organic Sulfur Compounds. XIII. The Oxidation Reaction of Alkoxycarbonylthioureas with Bromine

N-Alkoxycarbonylthioureas (A) were reacted with bromine in CHCl3 to afford sulfur, alkoxycarbonylureas (B), 3, 5-bis (alkoxycarbonylimino)-1, 2, 4-dithiazolidines (C), 3, 5-bis-(alkoxycarbonylamino)-1, 2, 4-thiadiazoles (D), 2-alkoxycarbonyl-5-alkoxycarbonylamino-3-imino-1, 2, 4-thiadiazolines (E) and 3-amino-5-alkoxycarbonylamino-1, 2, 4-thiadiazoles (F). This paper describes in detail on the confirmation of the structures of these reaction products.
