    Description / Table of Contents: NMR Spectroscopic Studies of 15N Labelled OxocyclophosphazanesThe completely 15N labelled cyclophosphazanes (15NMeP(OMe)O)3, (15NEtP(OEt)O)3, and (15NMeP(OMe)O)4 were prepared by rearrangement of the corresponding alkoxyphosphazenes and their 31P- and 15N-NMR spectra were investigated. On the case of the trimer compounds spectra of the ABB′XX′Y spin type were obtained; all coupling constants are relevant, and like the 15N chemical shifts they are found only by means of spectra simulations. The relative signs of the coupling constants 1JPN, 2JPP, 2JNN, and 3JPN were also obtained.
    Notes: Die vollständig 15N-markierten Cyclophosphazane (15NMeP(OMe)O)3, (15NEtP(OEt)O)3 und (15NMeP(OMe)O)4 wurden aus den entsprechenden Alkoxyphosphazenen dargestellt und sowohl 31P- als auch 15N-NMR-spektroskopisch untersucht. Bei den trimeren Verbindungen wurden Spektren vom Spintyp ABB'XX'Y erhalten; alle Kopplungskonstanten sind relevant, sie können wie die 15N-chemischen Verschiebungen nur auf dem Wege der Spektrensimulation erhalten werden. Es ergeben sich auch die relativen Vorzeichen für die Kopplungskonstanten 1JPN, 2JPP, 2JNN und 3JPN.

    Description / Table of Contents: Remarks on the Evidence of Rotational Isomers in Trichlorophosphazene-N-phosphoryl-dichloride by Means of NMR SpectroscopyBy means of 31P NMR spectroscopy no rotational isomers of trichlorophosphazene-N-phosphoryldichloride are separately observable, neither in spectra of the neat compound at the immediate range of the melting temperature nor on low temperature experiments in dimethylether solution until a temperature of 158 K.
    Notes: Mit Hilfe der 31P-NMR-Spektroskopie lassen sich keine Rotationsisomere des Trichlorphosphazen-N-phosphoryldichlorids getrennt nachweisen, weder in reiner Substanz im unmittelbaren Bereich der Schmelztemperatur noch bei Tieftemperaturmessungen in Dimethylether bis zu einer Temperatur von 158 K.

    Description / Table of Contents: NMR Spectroscopic Studies of Exocyclic 15N Labelled AmidochlorocyclotriphosphazenesSome exocyclic 15N labelled monoamidopentachlorocyclotriphosphazenes, N3P3Cl5X, and diamidotetrachlorocyclotriphosphazenes, N3P3Cl4X2, where X = 15NH2, 15NHMe, 15NMe2, or 15NHPh, were prepared, and the 31P- and 15N-NMR spectra were recorded. The chemical shift values δP and δN and the coupling constants 1JPN and 3JPN are discussed.
