Phosphazenes, XXXVIII. (Methylenamino)phosphinesAs shown by reactions and n. m. r. shift data the newly prepared (methylenamino)phosphines X2P—N =CR2 are both nucleophilic and electrophilic (at the phosphorus and carbon end, repectively). (Alkoxymethylenamino)phosphines (R = OAlkyl) resemble alkoxyphosphines as they rearrange with methyl iodide (in a Michaelis-Arbusov type reaction but via a stable phosphonium iodide) to form acylphosphinimines.
Notes:
Methylenamino-phosphine X2P — N= CR2 besitzen im P ein nucleophiles. im C ein elektrophiles Zentrum. 31P- und 1H-NMR-Verschiebungen lassen den Einfluß der Substituenten erkennen. Alkoxymethylenamino-phosphine lagern mit Methyljodid im Sinne einer verzögerten Michaelis-Arbusow-Reaktion über ein stabiles Phosphoniumjodid in das Acylphosphinimin um.
