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 (Bu 4 N) 2 P 16 in the solid state. The reaction was scaled up to gram quantities by using a flow‐chemistry process.
