Abstract

A method of synthesizing soluble polyphosphides using shelf-stable reagents and common organic solvents is presented. A reaction between an alkali metal alkoxy compound or alkali metal alkyl thiolate compound 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.
