    Description / Table of Contents: Salts of Halogenophosphoric Acids. XIX Formation and Identification of Stable Intermediates on the Reaction of Fluoride with Phosphorus OxychlorideBy reaction of POCl3 with fluorides of tertiary amines in the presence of the free amines the oxo-fluorophosphates [F2P(O—O—PF5)]-, [OPF5]2-, and [OPF4]- are formed as intermediates on the way to [PF6]-. The compounds were characterized by NMR spectroscopy.
    Notes: Bei der Reaktion von POCl3 mit Fluoriden tertiärer Ammoniumbasen in nichtwäßriger, basischer Lösung werden als Zwischenprodukte auf dem Weg zum [PF6]- das Heptafluorodiphosphat [F2P(O)—O—PF5]- sowie die Oxofluorophosphate [OPF5]2- und [OPF4]- gebildet und NMR-spektroskopisch charakterisiert.
