    Description / Table of Contents: Formation and N.M.R.-Spectroscopic Characterization of Alk-(ar-)oxy Derivatives of Trichlorophosphazene-N-phosphoryldichloride, Cl3P=N—P(O)Cl2, Imido- and N-Methylimidodiphosphoryltetrachloride, Cl2P(O)NHP(O)Cl2 and Cl2P(O)N(CH3)P(O)Cl2The ester chlorides and esters P2NOCl5-x(OR)x (x = 1-5), P2(NH)O2Cl4-x(OR)x (x = 1-4) and P2(NCH3)O2Cl4-x(OR)x (x = 1-4) derived from the title compounds by substitution of chlorine atoms by alk- or aroxy groups are characterized by their 31P-n.m.r. data. The possibilities for forming these compounds by alcoholysis, chloridolysis, dealkylation and P—N-bond formation are discussed.
    Notes: Die sich von den Titelverbindungen durch Substitution der Chloratome durch Alk- bzw. Aroxygruppen ableitenden Esterchloride und Ester P2NOCl5-x(OR)x (x = 1-5), P2(NH)O2Cl4-x(OR)x (x = 1-4) und P2(NCH3)O2Cl4-x(OR)x(x = 1-4) werden 31P-NMR-spektroskopisch charakterisiert. Die Möglichkeiten zur Bildung dieser Verbindungen durch Alkoholyse, Chloridolyse, Entalkylierungs- und P—N-Bindungsknüpfungsreaktionen werden vorgestellt.

    Description / Table of Contents: NMR Spectroscopic Studies of 15N Labelled N-Methyl-imidodiphosphoric Acid Derivatives15N labelled compounds (EtO)mCl2-m(O)P—NMe—P(O)(OEt)nCl2-n (m = 0-2, n = 0-2) were prepared as a mixture and investigated by means of 31P and 15N NMR spectroscopy. The chemical shift values δP and δN, and the coupling constants 1JPN and 2JPP are discussed and interpreted qualitatively by semiempirical quantumchemical calculations (CNDO/2) using POPLE'S ΔE-model.
    Notes: 15N-markierte Verbindungen der Substitutionsreihe (EtO)mCl2-m(O)P—NMe—P(O)(OEt)nCl2-n (m = 0-2, n = 0-2) wurden im Reaktionsgemisch synthetisiert und mit Hilfe der 31P- und 15N-NMR-Spektroskopie untersucht. Die chemischen Verschiebungen δP und δN sowie die Kopplungskonstanten 1JPN und 2JPP werden diskutiert und qualitativ mit Hilfe halbempirischer quantenchemischer Rechnungen (CNDO/2) im Rahmen des POPLE-schen ΔE-Modells interpretiert.
