    Description / Table of Contents: On the „HCl- Condensation“ of Phosphorus OxytriamideThe reaction of HCl with phosphorus oxytriamide suspended in ether leads to highly cross-linked imidopolyphosphates. By substitution of amido group by chlorine atoms amidochlorides of phosphoric acid are also formed which are soluble in ether. Only traces of oligomeric μ-imidophosphoric acid amides are obtained. The intermediate formation of phosphorylimide amide, OP(=NH)NH2, and phosphoryl imide chloride, OP(=NH)CI, is assumed to explain the experimental results.
    Notes: Die Reaktion von HCl mit Phosphoroxidtrimid in ätherischer Suspension führt zur Bildung stark vernetzter Imidopolyphosphate. Durch Substitution von Amidgruppen durch Chloratome entstehen außerdem ätherlösliche Amidchloride der Phosphorsäure. Oligomere μ-Imidophosphorsäureamide werden nur in Spuren erhalten. Zur Interpretation der experimentellen Befunde wird die intermediäre Bildung von Phosphorylimidamid, OP(=NH)NH2, und Phosphorylimidchlorid, OP(=NH)CI, angenommen.

    Description / Table of Contents: On the Constitution of the Trimethylsilyl Derivatives of Imidodiphosphoryl CompoundsEsters and dialkylamides of the imidodiphosphoric acid react with hexamethyl-disilazane to form trimethylsilyl derivatives. 1H-, 29Si-, and 31P-NMR data show the trimethylsilyl group to be bond to oxygen with rapid reversible exchange between both phosphoryloxygen atoms.
    Notes: Ester und Dialkylamide der Imidodiphosphorsäure reagieren mit Hexamethyldisilazan zu den Trimethylsilylderivaten. Aus 1H-, 29Si- und 31P-NMR-Daten folgt, daß die Trimethylsilylgruppe über Sauerstoff gebunden ist und einem schnellen reversiblen Austausch zwischen den beiden Phosphorylsauerstoffatomen unterliegt.

    Description / Table of Contents: Imidodiphosphoric Acid EstersImidodiphosphoryl tetrachloride reacts with aliphatic alcohols (C1-C3) as well as with sodium phenolate to form tetraalkylesters or tetraphenylesters of the imidodiphosphoric acid, resp. The tetraalkylesters (alkyl = methyl, ethyl, n-propyl) are also formed by reaction of trichlorphosphazene phosphoryldichloride, Cl3P=N—POCl2, with the corresponding alcohols. The purification of the esters can be reached by destillation of their silyl derivatives followed by desilylation. The esters are associated by intermolecular O…H…O hydrogen bonds.
    Notes: Imidodiphosphoryltetrachlorid reagiert mit Alkanolen (C1-C3) zu den Tetraalkylestern und mit Natriumphenolat zum Tetraphenylester der Imidodiphosphorsäure. Die Tetraalkylester (Alkyl = Methyl, Äthyl, n-Propyl) werden auch bei der Umsetzung von Trichlorphosphazenphosphoryldichlorid, Cl3P=N—POCl2, mit den entsprechenden Alkoholen gebildet. Die Reinigung der Ester gelingt durch Destillation ihrer Silylderivate und deren anschließender Desilylierung. Die Ester sind über intermolekulare O … H … O-Wasserstoffbrücken assoziiert.

    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.

    Description / Table of Contents: Reaction of the Two-component System Trialkylphosphite/Carbon Tetrachloride with Nucleophiles Containing Hydrogen. 2. Reaction with Ammonia and AminesAmmonia and primary amines react with the two-component system trialkylphosphite/carbon tetrachloride yielding diester-amides of phosphoric acid, (RO)2P(O)NHR′. If an excess of amine is used compounds of the type ROP(O)(NHR′)2 and OP(NHR′)3 are formed too. By the reaction of (RO)3P/CCl4 in presence of secondary and tertiary amines the first reaction product is (RO)2P(O)CCl3 which yields with the amine [NRR′R″R″′]+[Cl3CP(OR)O2]-; (R = Et, Bu).
    Notes: Ammoniak und primäre Amine reagieren mit dem Zweikomponenten-system Trialkylphosphit/Tetrachlokohlenstoff zu Diesteramiden der Phosphorsäure, (RO)2P(O)NHR′. Bei Aminüberschuß werden auch Verbindungen des Typs ROP(O)(NHR′)2 und OP(NHR′)3 gebildet. Bei der Reaktion von (RO)3P/CCl4 in Gegenwart sekundärer und tertiärer Amine entsteht zunächst (RO)2 P(O)CCl3, das mit dem Amin zu [NRR′R″R′]+[Cl3CP(OR)O2]- reagiert; (R = Et, Bu).
