    Description / Table of Contents: Perfluoroalkylated Acids of Phosphorus. II. On Trifluoromethyl Benzene Phosphinic AcidBis-(trifluoromethyl-benzene) phosphinic acid anhydride 1, easily formed by CF3COOH and C6H5PCl2, yields on reaction with aqueous Na2CO3 solution the sodium salt of trifluoromethyl benzene phosphinic acid 2. The acid itself is isolated by ion exchange as a hygroscopic and highly acidic substance.
    Notes: Das aus CF3COOH und C6H5PCI2 leicht zugängliche Bis-(trifluormethyl-benzol-)phosphinsäure-anhydrid 1 läßt sich mit wäßriger Na2CO3-Lösung zum Na-trifluormethyl-benzol-phosphinat umsetzen, aus dem über Ionenaustausch die freie, hygroskopische und stark acide Trifluormethyl-benzol-phosphinsäure 2 dargestellt werden konnte.

    Description / Table of Contents: Perfluoroalkylated Acids of Phosphorus. III. Diphenyl Trifluoromethyl and Diphenyl Trifluoroacetyl Phosphinic Oxide as Intermediates in the Preparation of Diphenyl Phosphinic Acid(Bis-Trifluoromethyl Diphenyl Orthophosphinic Acid) Anhydride(C6H5)2P(O)CF3 (3) and (C6H5)2P(O)C(O)CF3 (2) were identified as intermediates in the thermal rearrangement and condensation of (C6H5)2POCOCF3 by IR-, NMR- and mass spectroscopy. An improved method for the preparation of (C6H5)2P(O)—O—P(C6H5)2(CF3)2 is given.
    Notes: (C6H5)2P(O)CF3 3 und (C6H5)2P(O)C(O)CF3 2 wurden IR-, NMR- und massenspektroskopisch als Zwischenprodukte der thermischen Umlagerung und Kondensation von (C6H5)2POCOCF3 nachgewiesen. Eine verbesserte Darstellungsmethode für (C6H5)2P(O)—O—P(C6H5)2(CF3)2 wird angegeben.
