    Description / Table of Contents: Reaktionen mit Thiazolo [3,2-b]s-triazol-3(2H)-onen5-Aryl-3-carboxymethylmercapto-1,2,4-triazole 2 werden zu 6-Arylthiazolo[3,2-b]s-triazol-3(2H)-onen 3 cyclisiert. Die Strukturzuordnung wurde anhand von IR- und NMR-Spektren getroffen. 2-Arylmethylen-6-aryl-thiazolo[3,2-b]s-triazol-3(2H)-one 7 wurden nach verschiedenen Methoden erhalten. Die Verbindungen 3 kuppelten mit diazotierten Anilinen zu den 2-Arylhydrazono-6-aryl-3-oxo-2,3-dihydro-thiazolo[3,2-b]s-triazolen 8. Unter der Einwirkung von Aminen auf 3a wird der Thiazolonring unter Bildung der substituierten 5-Phenyltriazolyl-(3)-mercapto-acetamide 9 geöffnet.
    Notes: 5-Aryl-3-carboxymethylthio-1,2,4-triazoles 2 are cyclised to 6-arylthiazolo[3,2-b]-s-triazol-3(2H)-ones 3. This structural assignment has been based on IR and NMR spectra. 2-Arylmethylene-6-arylthiazolo[3,2-b]-s-triazol-3(2H)-ones 7 were prepared by several methods. Compounds 3 coupled with diazotised anilines to give 2,3-dihydro-6-arylthiazolo[3,2-b]-s-triazole-2,3-dione 2-arylhydrazones 8. The action of amines on 3a opens the thiazolone ring with the formation of substituted (5-phenyltriazol-3-ylthio)-acetamides 9.
