Abstract

Abstract Phosphine, generated from elemental phosphorus in the system KOH-toluene-H2O, reacts with vinyl sulfides under free radical conditions (AIBN, dioxane, 65–70° C, atmospheric pressure) to form regiospecifically tris [2-(organylthio) ethyl] phosphines, which are readily oxidized in air to corresponding tris [2-(organylthio) ethyl] phosphine oxides.
