Using phenyliodine diacetate as an oxidant and nickel acetate as a promoter, a wide range of unsymmetric thiosulfonates could be furnished easily in moderate to excellent yields starting from N-substituted O-thiocarbamates and sodium sulfinates. This protocol features mild conditions, short reaction times, and high atomic utilization, which can provide an alternative method for the synthesis of unsymmetric
使用苯碘二乙酸盐作为氧化剂和乙酸镍作为促进剂,可以从 N-取代的O-硫代氨基甲酸盐和亚磺酸钠开始以中等至优异的产率轻松提供各种不对称硫代磺酸盐。该协议具有条件温和、反应时间短、原子利用率高等特点,可为不对称硫代磺酸盐的合成提供一种替代方法。此外,该反应可按克级放大,显示出潜在的工业应用价值。
