An efficient procedure for the synthesis of thiophosphates is described. Without using any metallic catalyst or base, the direct sulfur–phosphorus coupling reaction of disulfides and dialkyl trimethylsilyl phosphite (DTSP) was carried out under solvent‐free reaction conditions in moderate to excellent yields with good functional group compatibility. The reaction conditions represent an advance over established methods not only in omitting the need for expensive catalysts or solvents, but also in shortening the reaction time significantly.These transformations are easy to conduct and can be readily applied to gram‐scale preparation.

在纯净条件下二硫化物与亚磷酸甲硅酯的反应生成硫代磷酸盐

描述了合成硫代磷酸盐的有效方法。在不使用任何金属催化剂或碱的情况下，二硫化物与亚磷酸二烷基三甲基甲硅烷基酯（DTSP）的直接硫-磷偶联反应在中等至极好的收率下进行，具有良好的官能团相容性。反应条件代表了一种既定方法的进步，不仅消除了对昂贵催化剂或溶剂的需求，而且显着缩短了反应时间。这些转化过程易于进行，可轻松用于克级制备。
