2-Halogen-1,3,2λ3- und 2,2,2-Trihalogen-1,3,2λ5-Dioxaphospholane

Die Reaktion des Dilithium-perfluorpinakolats mit Phosphortrihalogeniden fuhrt zu 1,3,2λ3-Dioxaphospholanen XP[OC(CF3)2C(CF3)2O] (X = F, Cl, Br). Durch oxidative Addition von Chlor bzw. Brom entstehen daraus 1,3,2λ5-Dioxaphospholane XY2P[OC(CF3)2C(CF3)2O] (X = F, Cl, Br; Y = Cl, Br). Die Phosphoroxyhalogenide POX3 (X = F, Br) ergeben mit Li2[OC(CF3)2C(CF3)2O] die 1,3,2λ5-Dioxaphospholane X3P[OC(CF3)2C(CF3)2O] und den Diphorphorsaureester O{P(:O)[OC(CF3)2C(CF3)2O]}2. 2-Halogeno-1,3,2λ3- and 2,2,2-Trihalogeno-1,3,2λ5-dioxaphospholanes The reaction of dilithium perfluoropinacolate with phosphorus trihalides gives rise to 1,3,2λ3-dioxaphospholanes, XP[OC(CF3)2C(CF3)2O] (X = F, Cl, Br). Oxidation with chlorine and bromine furnishes the 1,3,2λ5-dioxaphospholanes, XY2P[OC(CF3)2C(CF3)2O] (X = F, Cl, Br; Y = Cl, Br). The phosphory Ihalides. POX3 (X = F, Br) react with Li2[OC(CF3)2C(CF3)2O] to give 1,3,2λ5-dioxaphospholanes, X3P[OC(CF3)2C(CF3)2O] and the diphosphate ester, O{P(:O)[OC(CF3)2C(CF3)2O]}2.
