Simple and Convenient Method for the Synthesis of Aryltellurophosphates Catalyzed by Cesium Hydroxide

Abstract In the presence of a catalytic amount cesium hydroxide, the corresponding aryltellurophosphates can be obtained by the reactions of dialkyl phosphites with diaryl ditellurides in excellent yield at room temperature, using dimethylsulfoxide as solvent. The possible reaction mechanism was discussed. The method could provide a new and expedient path for the preparation of aryltellurophosphates. GRAPHICAL ABSTRACT
