method for the synthesis of 1,3-dibenzenesulfonylpolysulfane (DBSPS), which further reacts with boronic acids to afford thiosulfonates. Commercially available boron compounds greatly expanded the range of thiosulfonates. Experimental and theoretical mechanistic investigations suggested that DBSPS could provide both thiosulfone fragments and dithiosulfone fragments, but the generated aryl dithiosulfonates
在此,我们提供了一种合成 1,3-二苯磺酰基聚硫烷 (DBSPS) 的新方法,该方法可进一步与硼酸反应生成硫代磺酸盐。市售的硼化合物极大地扩展了硫代磺酸盐的范围。实验和理论机理研究表明,DBSPS 可以同时提供硫代砜片段和二硫代砜片段,但生成的芳基二硫代磺酸盐不稳定,会分解为硫代磺酸盐。
