Soluble polyphosphide anions were successfully generated in a number of organic solvents by the reaction between shelf‐stable red phosphorus and potassium ethoxide. The species were identified by 31P NMR spectroscopy in solution and by X‐ray crystal‐structure determination of (Bu4N)2P16 in the solid state. The reaction was scaled up to gram quantities by using a flow‐chemistry process.
Roter Phosphor In ihrer Zuschrift auf S. 3972 ff. beschreiben M. Shatruk, D. T. McQuade et al. die Aktivierung von rotem Phosphor durch nukleophilen Angriff von KOEt unter Bildung löslicher Polyphosphide. Die Reaktion wurde in einem Fließreaktor hochskaliert. Bild: Kateryna Zavadska.
