A method to assemble (hetero)aryl sulfonamides via the reductive coupling of aryl sulfinates and nitroarenes is reported. Various reducing conditions with sodium bisulfite and with or without tin(II) chloride in DMSO were developed using an ultrasound bath to improve reaction homogeneity and mixing. A range of (hetero)aryl sulfonamides bearing a selection of functional groups were prepared, and the
报道了一种通过芳基亚磺酸盐和硝基芳烃的还原偶联组装(杂)芳基磺酰胺的方法。使用超声波浴开发了在 DMSO 中使用亚硫酸氢钠以及含或不含氯化锡 (II) 的各种还原条件,以改善反应均匀性和混合。制备了一系列带有精选官能团的(杂)芳基磺酰胺,并研究了转化机制。这些研究使我们提出了亚硝基芳烃中间体的形成,这是通过独立的分子偶联策略建立的。
