Dicyanphosphid-Reaktionen [1] / Dicyanophosphide Reactions [1]

Abstract

31P (and, as applicably, 77Se) NMR spectra show P(CN)2 - to take up one or two atoms of sulfur or selenium and to react with a variety of anionic phosphorus nucleophiles. Displacement of the first cyanide gives cyanodiphosphides, cyanophosphinidene-phosphates, -phosphinates, -thiophosphinates and -iminophosphinates, respectively. Displacement of the second cyanide gives triphosphates and triphosphinates which are otherwise known as products from the nucleophilic P4 degradation.
