We realized an interesting palladium-catalyzed aminosulfonylation of aryl iodides by using Na2SO3 as a cheap SO2 source. In most cases, the yields were comparable to those reported by using the 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABCO·2SO2, DABSO) as the SO2 source.
我们通过使用 Na2SO3 作为廉价的 SO2 来源,实现了一种有趣的钯催化的芳基碘化物的氨基磺酰化。在大多数情况下,产率与使用 1,4-二氮杂双环 [2.2.2] 辛烷双(二氧化硫)加合物(DABCO·2SO2,DABSO)作为 SO2 源所报告的产率相当。
