    Description / Table of Contents: Substitution Reactions and Oxidative Addition on 2-Chloro-4, 4, 5, 5-tetrakis (trifluoromethyl)-1, 3, 2-dioxaphospholaneSubstitution of chlorine in the title compound 1 yields the phosphites XP[OC(CF3)2C(CF3)2O] (2: X = I, 4 : X = OCH(CF3)2, 5: X = OC(O)CF3, 7: X = OSiMe3). Compound 2 is easily reduced by hydrogen iodide and mercury to give HP[OC(CF3)2C(CF3)2O], 3. The acylphosphite 5 decomposes into trifluoracetic acid anhydride and the μ-oxo diphosphite 6 at elevated temperatures. 6 is obtained also in the reaction of triphenylhydroxystannane and 1, whereas trimethylhydroxystannane formes the phosphonic acid ester 11 which furnishes the phosphoric acid ester 12 upon reacting with hexafluoroacetone. 12 is obtained directly from the monoammonium-salt of hexafluoroacetonehydrate 13 and 1 exhibiting a prototropic rearrangement. Compound 7 is oxidized by chlorine to yield the trichlorophosphorane 9 and the diphosphate 10. Antimony pentachloride and iodochloride oxidize 1 to give the dichlorophosphonium hexachloroantimonate 14 and the trichlorophosphorane 9, respectively.
    Notes: Durch Substitution von Chlor in der Titelverbindung, 1, werden Phosphite XP[OC(CF3)2C(CF3)2O] (2: X = I, 4: X = OCH(CF3)2, 5: X = OC(O)CF3, 7: X = OSiMe3) dargestellt. Das Iodphosphit 2 wird mit Hilfe von Iodwasserstoff und Quecksilber zu HP[OC(CF3)2C(CF3)2O], 3 reduziert. Bei höheren Temperaturen zerfällt das Acylphosphit 5 in Trifluoressigsäureanhydrid und das sauerstoffverbrückte Diphosphit 6, das auch durch Umsetzung von Triphenylhydroxystannan mit 1 erhalten wird. Verbindung 7 wird durch Chlor zu dem Phosphoran 9 und dem Diphosphat 10 oxydiert. Trimethylhydroxystannan reagiert zu dem Phosphonsäureester 11, der mit Hexafluoraceton in den Phosphorsäureester 12 übergeht. 12 ist direkt aus 1 mit Monoammoniumsalz des Hexafluoracetonhydrats 13 in einer Umlagerungsreaktion zugänglich. Antimonpentachlorid oxydiert 1 zu dem Dichlorphosphoniumsalz 14, Iodchlorid zu dem Trichlorphosphoran 9.
