Ylidenmalonitrilphosphines (NC)2C=C(X)PRR′Ylidenmalonitrilphosphines of the general formula (NC)2C=C(X)PRR′ (X = Alkyl, Cl, NH2, PRR′; R = Ph, R′ = Ph, H) are prepared under different conditions from (NC)2C=C(X)Cl (X = Alkyl, Cl, NH2) and prim. or sek. phosphines and their monosubstituted alkali or trimethylsilyl derivatives respectively. The synthesis as well as the behaviour of (NC)2C=C(X)PRR′ are compared with the corresponding oxygen analogues of the type O=C(X)PRR′. The structure of the title compounds are elucidated by investigation of their mass, i.r., and n.m.r. spectra.
Notes:
Ylidenmalonitrilphosphine der allgemeinen Formel (NC)2C=C(X)PRR′ (X = Alkyl, Cl, NH2, PRR′; R = Ph, R′ = H, Ph) lassen sich unter verschiedenen Reaktionsbedingungen aus (NC)2C=CXCl (X = Alkyl, Cl, NH2) und prim. oder sek. Phosphinen bzw. deren monosubstituierten Alkali- sowie Trimethylsilylderivate herstellen. Sowohl Synthese als auch Eigenschaften der Ylidenmalonitrilphosphine werden mit den Sauerstoffanaloga des Typs O=C(X)PRR′ verglichen und IR-, NMR- sowie massenspektroskopisch charakterisiert.
