Darstellung von Dikalium‐difluorodiphosphat durch thermische Reaktion von Tetraphosphordekaoxid mit Kaliumfluorid

Abstract

vgl. dazu (S)]. Auf die nahe Verwandtschaft zur ,,von-Richter-Carboxylierungsreaktion" [lo] (Nucleophil: CNO; anionische Austrittsgruppe: N02Q; hypothetische Zwischenstufe (13) ; Losungsmittel Athanol!) sei hingewiesen.

Synthesis and characterisation of trimethylsilyl phosphorohalidates: Me3SiOP(O)FX (X = Cl, Br) and (Me3SiO)2P2O3F2

“…However, a band shape analysis and simulation of spectrum gave coupling constants that compare well with those of the [P 2 O 5 F 2 ] 2À ion ( Table 3). The NMR parameters of [P 2 O 5 F 2 ] 2À were re-determined in the present study because the literature data [18,19] showed considerable differences in the magnitudes of 2 JðPP 0 Þ (2.5 and 17.1 Hz). The established value 13.6 Hz is commensurable with magnitudes of both 2 JðPPÞ constants (12.1 and 14.5 Hz) reported for the anion [FPO 2 OPO 2 OPO 3 ] 4À [20].…”
