Abstract

Abstract: 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 31 P NMR spectroscopy in solution and by X‐ray crystal‐structure determination of (Bu4 N)2 P16 in the solid state. The reaction was scaled up to gram quantities by using a flow‐chemistry process.
