    Description / Table of Contents: Pentafluoro-orthoselenic Acid Disulfurylfluoride and Pentafluoro-orthoselenic Acid TrifluoroacetateFrom the reaction of pentafluoro-orthoselenic acid and sulfur trioxide only one compound could be prepared having a pentafluoroselenium group: F5Se-O-SO2-O-SO2F. In fluorine magnetic resonance of this compound a coupling over a range of six bonds can be observed. Selenium oxide tetrafluoride could not be prepared. The reaction of mercury bis(pentafluoro-orthoselenate) with trifluoroacetylchloride yields pentafluoro-orthoselenic acid trifluoroacetate.
    Notes: Bei der Reaktion von Pentafluoro-orthoselensäure mit Schwefeltrioxid tritt als einzige Verbindung mit erhaltener Pentafluoroselen-Gruppe F5Se-O-SO2-O-SO2F auf, deren 19F-Kernresonanz eine Kopplung über sechs Bindungen hinweg anzeigt. Selenoxidtetrafluorid, SeOF4, wurde nicht gefunden. - Pentafluoro-orthoselensäure-trifluoracetat entsteht bei der Reaktion von Quecksilber-bis(pentafluoro-orthoselenat) mit Trifluoracetylchlorid.

    Description / Table of Contents: Halogen Derivatives of Pentafluoroorthoselenic AcidPreparation and properties of F5SeOCl, F5SeOBr, (F5SeO)3Br, and of the known compound F5SeOF are given The known peroxide F5SeO-OSeF5 is a by-product in the synthesis of F5SeOF. The formal anhydride of pentafluoroorthoselenic acid, F5SeOSeF5, is the main product of the decomposition of the xenon salt (F5SeO)2Xe Iodine compounds like F3SeOJ and (F5SeO)3J are not stable and could only be detected by their 19F n.m.r. spectra.
    Notes: Darstellung und Eigenschaften der Verbindungen F5SeOCl, F5SeOBr, (F5SeO)3Br neben dem schon bekannten F5SeOF werden beschrieben Bei der Synthese des letzteren fällt auch das bekannte Peroxid F5SeO-OseF5 an. Das formale Anhydrid der Pentafluoroorthoselensäure, F5SeOSeE5, konnte bei der Zersetzung des Xenonsalzes (F5SeO)2 Xe erhalten werden Entsprechende Jodverbindungen, F5SeOJ und (F5SeO)3J, sind zersetzlich und konnten nur anhand ihrer 19F-NMR-Spektren nachgewiesen werden.

    Description / Table of Contents: On the Way to Pentafluorocyclopentadienyl Anion: 1,2,3,4,5-Pentafluorocyclopentadiene1,2,3,4,5-Pentafluorocyclopentadiene (8) was obtained in three steps from hexachlorocyclopentadiene (2). It is a typical cyclopentadiene. Thus, it dimerizes reversibly already at - 78°C.
