A palladium-catalyzed desulfonative carbonylation of thiosulfonates has been explored. Without any additive, a series of S-aryl/alkyl benzenesulfonothioates were successfully transformed to thioesters in moderate to excellent yields by SO2 extrusion and CO insertion under the pressure of 1 bar of CO. The solvent dimethylacetamide (DMAc) facilitated this desulfonative carbonylation due to its high absorbing
已经探索了硫代磺酸盐的钯催化的脱磺羰基化。在不使用任何添加剂的情况下,在 1 bar CO 的压力下,通过 SO 2挤出和 CO 插入,一系列S-芳基/烷基苯硫代磺酸盐成功地转化为硫酯,产率适中。对SO 2的高吸收能力。
