    Description / Table of Contents: Synthesis and Properties of Lineary PhosphorylchlorphosphazenesThe phosphorylchlorphosphazenes, Cl2(O)P - [N=PCl2]n - Cl, (n = 1, 2, 3) react like POCl3 with hexamethyldisilazan forming silylamides, Cl2(O)P - [N = PCl2]n - NHSi(CH3)3, (n = 0, 1, 2, 3). From these are obtained the phosphorylchlorphosphazenes by reaction with PCl5 containing one group  - N = PCl2 more.
    Notes: Die Phosphorylchlorphosphazene, Cl2(O)P - [N=PCI2]n - Cl, (n = 1, 2, 3) reagieren ebenso wie POCl3 mit Hexamethyldisilazan zu den Silylamiden, Cl2(O)P - [N=PCl2]n - NHSi(CH3)3, (n = 0, 1, 2, 3), aus denen mit PCl5 die um eine Phosphazengruppe verlängerten Phosphorylchlorphosphazene erhalten werden.

    Oligomere μ-Imidophosphorsäurechloride und -amide (1975)

    Description / Table of Contents: Oligomeric μ-Imidophosphoric Acid Chlorides and AmidesOligomeric μ-imidophosphoric acid chlorides. Cl2(O)P—[NH—P(O)Cl]n—Cl, (n = 1, 2, 3) are obtained by solvolysis of the linear phosphorylchlorphosphazenes, Cl2(O)P—[N=PCl2]n—Cl, with the stoichiometric amount of anhydrous formic acid. The chlorides react with ammonia forming the amides. The amides are characterized by paper and gel chromatography. Course and rate of hydrolysis of diimidotriphosphoric acid pentaamide depend on pH.
    Notes: Die oligomeren μ-Imidophosphorsäurechloride, Cl2(O)P—[NH—P(O)Cl]n—Cl, (n = 1, 2, 3) werden durch Solvolyse der linearen Phosphorylchlorphosphazene, Cl2(O)P—[N=PCl2]n—Cl, mit der stöchiometrischen Menge wasserfreier Ameisensäure erhalten. Mit Ammoniak reagieren die Chloride zu den entsprechenden Amiden. Die Charakterisierung der Amide erfolgte mittels Papier- und Gelchromatographie. Verlauf und Geschwindigkeit der Hydrolyse des Diimidotriphosphorsäurepentamids sind vom pH-Wert abhängig.

    Zur „HCl-Kondensation“ von Phosphorsäureamiden (1975)

    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.
