    Description / Table of Contents: 7-Aroyl-1H,7H-s-triazolo (1,3(2H)-diones, a New Class of Compounds from 5-Phenyloxazoles and 4-Phenyl-4H-1,2,4-triazole-3,5-dioneThe 5-aryloxazoles 2a-e and their substituted derivatives 8a-c and 10 react with 4-phenyl-4H-1,2,4-triazole-3,5-dione (3) to give the new 7-aroyl-1H,7H-s-triazolo[1,2-a]- s-triazole-1,3(2H)-diones 5a-e, 9a-c, and 11. The structure is deduced from the 13C NMR spectroscopic data of 5b, 9a, and 11. The mechanism is shortly discussed.
    Notes: Durch Umsetzung der 5-Aryloxazole 2a-e sowie der substituierten Vertreter 8a-c und 10 mit 4-Phenyl-4H-1,2,4-triazol-3,5-dion (3) lassen sich die neuen 7-Aroyl-1H,7Hs-triazolo[1,2-a]-s- triazol-1,3(2H)-dione 5a-e, 9a-c und 11 herstellen. Die Struktur wird aus den 13C-NMR-spektroskopischen Daten von 5b, 9a und 11 abgeleitet. Der Mechanismus der Bildung wird kurz diskutiert.
