Abstract

A method of generating soluble polyphosphides using solution chemistry is presented. A reaction between potassium ethoxide in THF/DME and shelf stable red phosphorus generated soluble polyphosphides in a variety of organic solvents with the 31P NMR spectrum being used to detect the species of polyphosphides produced.
