A new and general method for the synthesis of S-, Se-, and Te-aryl phosphorochalcogenoates (chalcogenophosphates) has been developed. S-P, Se-P, and Te-P bonds were formed by the coupling of readily available dialkyl phosphites with diaryl dichalcogenides at 30 ËC in dimethyl sulfoxide in the presence of catalytic amounts of copper iodide and diethylamine. The reaction proceeded smoothly without exclusion of moisture or air.

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.
