The synthesis of allylic thioethers arising from the reaction between phosphorothioate esters and alcohols is described. The synthesis is accomplished in one step by the addition of an exogenous alkoxide to the corresponding allylic phosphorothioate ester. It is demonstrated that this process is amenable to various functional groups and a wide variety of heterocycles. In contrast to conventional methods

A highly regioselective, Pd-catalyzed allylicfluorination of phosphorothioate esters is reported. This chemistry addresses several limitations of previously reported methods in which elimination and lack of reactivity were problematic. Preliminary mechanistic investigations reveal that these reactions are stereospecific and provide fluorinated products with net retention of stereochemical configuration
