Facile Conversion of Red Phosphorus into Soluble Polyphosphide Anions by Reaction with Potassium Ethoxide

Angew Chem Int Ed Engl. 2016 Mar 14;55(12):3904-8. doi: 10.1002/anie.201511186. Epub 2016 Mar 1.

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 (Bu4N)2P16 in the solid state. The reaction was scaled up to gram quantities by using a flow-chemistry process.

Keywords: NMR spectroscopy; flow chemistry; phosphorus allotropes; polyanions; structure elucidation.
