    Description / Table of Contents: Formation and Constitution of a Heterocyclic Phosphorus BetaineThe zwitter ionic 2,2,6,6-tetrakis(diethylamido)-4,4-Dioxo-1,3,5,2λ5,4λ5,6λ5-azadioxatriphosphorin (3) is formed as a cristalline byproduct in the reaction of octaethyl imidodiphosphoryl tetramide derivatives, {[(Et2N)2P(O)]2N}Y (Y = H, Na, SiMe3), with phosphorus(V) chlorides (PCl5, POCl3, ClP(O)(OEt)2). It is obtained from the primary reaction products in a secondary reaction. Its constitution was revealed by 31P-n.m.r.-spectroscopy and by synthesis of the 15N-labeled compound. From O-Diethoxyphosphorylated octaethyl imidodiphosphoryl tetramide the compound 3 is obtained only in presence of water traces and agents providing HCl like e. g. ClSiMe3 or ClP(O)(OEt)2.
    Notes: Bei der Umsetzung von Octaäthylimidodiphosphoryltetramid-Derivaten, {[(Et2N)2P(O)]2N}Y (Y = H, Na, SiMe3), mit Phosphor(V)-chloriden (PCl5, POCl3, ClP(O)(OEt)2) entsteht aus den primären Reaktionsprodukten in einer Folgereaktion das zwitterionische 2,2,6,6-Tetrakis(diäthylamido)-4,4-Dioxo-1,3,5,2λ5,4λ5,6λ5-azadioxatriphosphorin (3) als kristallines Nebenprodukt. Die Konstitutionsermittlung erfolgte mittels 31P-NMR-Spektroskopie und durch Synthese der 15N-markierten Verbindung. Aus dem O-Diäthoxyphosphorylierten Octaäthylimidodiphosphoryltetramid bildet sich 3 nur in Gegenwart von Wasserspuren und HCl-liefernden Reagenzien, wie ClSiMe3 oder ClP(O)(OEt)2.
