Abstract

Es wird über die Synthese einer Reihe von Alkoxy(aroxy)phosphoryltricyanmethaniden der bindungsisomeren Typen (RO)2P(O)NCC(CN)2 und (RO)2P(O)C(CN)3 berichtet. Synthesewege und IR-sowie 31P-NMR-Spektren der neuen Verbindungen lassen enge Beziehungen zu homologen Phosphoryl-pseudohalogeniden (RO)2P(O)NCY und (RO)2P(O)YCN (Y: NCN, O) erkennen und unterstreichen damit besonders deutlich den Pseudochalkogen-Charakter der C(CN)2-Gruppe.

Synthesis of Isomeric Alkoxy(aroxy)phosphoryl-tricyanmethanides, a Contribution to the Ambivalency of Pseudohalides

The synthesis of a series of alkoxy(aroxy)phosphoryltricyanmethanides of the isomeric types (RO)2P(O)NCC(CN)2 and (RO)2P(O)C(CN)3 is reported. Synthetic routes as well as IR- and 31P-NMR spectra are indicating close relations of the new compounds to homologeous phosphoryl-pseudohalides (RO)2P(O)NCY and (RO)2P(O)YCN (Y: NCN, O). Thus the presented results are clearly emphasizing the pseudochalcogen-character of the C(CN)2-group.
