    Description / Table of Contents: N,N′-Dihalogenoethanediirnidoyl DifluoridesThe title compounds XN=CF—CF=NX (13, 14, X = Cl, Br) are prepared in a simple way from the three components (CN)2, X2, and HgF2. The N-halogenated amino- or iminoperfluoroethanes Cl2N—CF2—CF2—NCl2 (11), ClN=CF—CF2—NCl2 (12), BrN=CF—CF2—NBr2 (15) and Br2N—CF2—CF2—NBr2 (16) were identified as further products. The structure of 14 was determined from single-crystal X-ray data.
    Notes: Die Titelverbindungen XN=CF—CF=NX (13, 14, X = Cl, Br) lassen sich in einfacher Weise aus den drei Komponenten Dicyan, X2 und HgF2 gewinnen. Als weitere Produkte konnten die N-halogenierten Amino- bzw. Iminoperfluorethane Cl2N—CF2—CF2—NCl2 (11), ClN=CF-CF2—NCl2 (12), BrN=CF—CF2—NBr2 (15) und Br2N—CF2—CF2—NBr2 (16) nachgewiesen werden. Aus Einkristall-Röntgenbeugungsdaten wurde die Struktur von 14 bestimmt.
