A facile synthetic method for unsymmetrical tertiary phosphine oxides is reported. Sequential treatment of phosphonodithioic acid S,S-di(p-tolyl) esters with two Grignard reagents enabled the stepwise introduction of different carbon substituents on the phosphorus atom. The chemical stability of dithioesters and monosubstituted thioesters has enhanced the utility of this method, rendering a wide range of organophosphorus compounds easily available.
