    Description / Table of Contents: By reacting anhydrous hydrofluoric acid with H3PO3, PF3 and the new fluoride PHF4 are formed at high yields. Hydrolysis of the latter compound in alkaline solutions gives quantitatively phosphorous acid and fluoride. PHF4 can be split into PF3 and HF easily.The reaction of H3PO2 with HF gives PH2F2 which hydrolyses quantitatively into H3PO2 and HF in alkaline solutions. Unsuccessful attempts were made to prepare PHF2 from PH2F3.
    Notes: Bei der Reaktion zwischen wasserfreier Flußsäure und H3PO3 entsteht PF3 und PHF4 in hohen Ausbeuten. Die Hydrolyse der letzteren Verbindung in alkalischen Lösungen ergibt quantitativ phosphorige Säure und Fluorid. PHF4 kann leicht in PF3 und HF gespalten werden. Die Reaktion von H3PO2 mit HF ergibt PH2F3, das in alkalischer Lösung quantitativ in H3PO2 und HF hydrolysiert. Versuche, aus PH2F3 PHF2 herzustellen, hatten keinen Erfolg.
