Notizen:
The hitherto unknown 1-aroyl-5-aryl-2-thiobiurets (5a-h) were synthesized by addition of mono arylureas (4) to aroyl isothiocyanates (3). Treatment of 1-aroyl-5-aryl-2-thiobiurets (5a-h) with alkali gave 5-aryl-2-thiobiurets (6a-e). Oxidation of 1-aroyl-5-aryl-2-thiobiurets (5d, f, h) with hydrogen peroxide in the presence of hydrochloric acid or bromine in chloroform gave 2-aryl-5-aroylamino-2,3-dihydro-1,2,4-thiadiazol-3-ones (7a-c).
