    Notes: Die von uns kürzlich beschriebenen 3-kernigen P-Verbindungen [1] haben nicht die Struktur von Methan-tris-phosphorylverbindungen 2, sondern sind Phosphorylamide von α-Arylaminomethan-bis-phosphorylverbindungen 3. Die Struktur von 3 wurde u. a. mittels 31P- bzw. 13C-NMR-Messungen sichergestellt.

    Description / Table of Contents: α-Substituted Phosphonates. XX. Investigations on the C - N-Rearrangement of Aminomethane Bis- and Tris-phosphoryl CompoundsAttempts to prepare aminomethane-bis-phosphoryl-compounds of the types 5, 9 and 13, i.e. with a NH-function on the methin-carbon-atom, yielded independently of the synthetic path in all cases by C-N-rearrangement of a phosphoryl-group the N-phosphorylated aminomethane-phosphonic acid esters 6, 10/11 and 14. The course of this rearrangement has been studied on characteristic examples.
    Notes: Versuche zur Darstellung von Aminomethan-bis-phosphorylverbindungen des Typs 5, 9 bzw. 13, also mit einer NH-Funktion am Methin-Kohlenstoffatom führen unabhängig vom Syntheseweg stets unter C-N-Wanderung eines Phosphorylrestes zu N-phosphorylierten Aminomethanphosphonsäureestern 6, 10/11 bzw. 14. Der Ablauf dieser Umlagerung wird an charakteristischen Beispielen untersucht.
