    Description / Table of Contents: Investigations on the Phosphorylation of Imidodiphosphoryl DerivativesDerivatives of esters and octaalkylamides of imidodiphosphoric acid, {[X2P(O)]2N}Y (X = OR, NR2; Y = H, Na, SiMe3, MgBr), react with phosphorus(V) chlorides exclusively under formation of O-phosphorylated products. No derivatives of nitridotriphosphoric acid are formed. O-Diethoxyphosphorylated phosphazenes, X2P(O)—N=PX2-O—P(O)(OEt)2, are obtained by using diethoxyphosphoryl chloride, (EtO)2P(O)Cl. Octaalkylamides react with PCl5 to form tetrachlorophosphonium compounds containing the PCl4 group chelate-like surrounded by the octaalkyl imidodiphosphoryl tetramide anion. The product of the reaction of octaalkyl imidodiphosphoryl tetramide sodium and POCl3 seems to have an analogous constitutions.
    Notes: Derivate von Estern und Octaalkylamiden der Imidodiphosphorsäure, {[X2P(O)]2N}Y (X = OR, NR2; Y = H, Na, SiMe3, MgBr), reagieren mit Phosphor(V)-chloriden ausschließlich unter Bildung O-phosphorylierter Produkte. Es entstehen keine Derivate der Nitridotriphosphorsäure. Mit Diäthoxyphosphorylchlorid, (EtO)2P(O)Cl, bilden sich O-Diäthoxyphosphorylierte Phosphazene, X2P(O)—N=PX2-O—P(O)(OEt)2. Die Octaalkylamide reagieren mit PCl5 zu Tetrachlorophosphoniumverbindungen, in denen die PCl4-Gruppe vom Octaalkylimidodiphosphoryltetramid-Anion chelatartig umgeben ist (IV). Eine analoge Konstitution scheint das Reaktionsprodukt von Octaäthylimidodiphosphoryltetramid-Natrium mit POCl3 zu haben.
