Reaktionen des Bromylfluorids, BrO₂F: Gemischtvalente Brom‐Sauerstoff‐Kationen, Br₃O₄⁺ und Br₃O₆⁺

Konrad Seppelt

Abstract: Für das instabile und extrem reaktive BrO2F wird eine verlässliche Synthese beschrieben. Dieses wird in BrO2+ SbF6−, BrO2+ AsF6− und BrO2+ AsF6−⋅2 BrO2F umgewandelt. Letzteres zerfällt in Br3O4⋅Br2+ AsF6− mit fünf‐, drei‐ und einwertigem Brom. Mit HSO3CF3 bildet sich BrO2+H(SO3CF3)2−. Überschuss an BrO2F ergibt gemischtvalentes Br3O6+OSO3CF3− mit fünf‐ und dreiwertigem Brom. Reaktionen von BrO2F und MoF5 in SO2ClF oder CH2ClF ergeben Cl2BrO6+Mo3O3F13−. Die Reaktionen von BrO2F mit (CF3CO)2O und NO2 ergeben O2B… Show more

After 200 Years: The Structure of Bleach and Characterization of Hypohalite Ions by Single‐Crystal X‐Ray Diffraction**

We report the first X-ray single crystal structures of hypochlorite (ClO À ) and hypobromite (BrO À ) salts, including hydrated sodium hypochlorite, a staple of the chlorine industry and ubiquitous bleaching and disinfection agent for almost 200 years. The structures, supported by variable-temperature Raman spectroscopy on individual crystals and periodic density-functional theory (DFT) calculations, provide insight into solid-state geometry and supramolecular chemistry of hypohalite ions.

A systematic study of halogenate(I/III) anions with polyatomic ligands is presented. The bis(perfluoro‐tert‐butoxy) halogenates(I) [X(OC4F9)2]−, X=Cl, Br, I, of chlorine, bromine, and iodine are prepared as their tetraethylammonium salts and characterized with IR, Raman, and NMR spectroscopic methods, as well as single‐crystal X‐ray diffraction analyses. Spectroscopical data are supported by quantum‐chemical calculations. Additionally, the bonding situation of the species in question are analyzed and discussed. Furthermore, the oxidation to the corresponding halogenate(III) derivatives was studied. For [Br(OC4F9)2]−, oxidation with elemental fluorine gave [BrF2(OC4F9)2]−. Iodide was directly oxidized by ClOC4F9 to the IIII species [I(OC4F9)4]−, which is a surprisingly inert anion that might be used as a weakly coordinating anion (WCA) in the future. For [Cl(OC4F9)2]−, the decomposition products of the synthetic approaches towards a chlorine(III) system were analyzed.
