摘要
In the presence of a catalytic amount of cesium hydroxide, the corresponding S-aryl phosphorothioates can be obtained by the reactions of dialkyl phosphites with diaryldisulfides in excellent yields at room temperature, using DMSO as a solvent. The reaction mechanism was discussed. The method provides a new and expedient path for the preparation of S-aryl phosphorothioates.
