prepared from aryl iodides and the sulfur dioxide surrogate DABSO, under the action of a palladium(0) catalyst, are transformed in a one-pot process to a variety of functionalized sulfonamides. The sulfinate to sulfonamide transformation is achieved by simple treatment with an aqueous solution of the relevant amine and sodium hypochlorite (bleach). A broad range of amines, including anilines, and amino
芳基亚磺酸铵,方便地由芳基碘化物和二氧化硫替代物 DABSO 制备,在钯 (0) 催化剂的作用下,在一锅法中转化为各种功能化的磺酰胺。亚磺酸盐向磺酰胺的转化是通过用相关胺和次氯酸钠(漂白剂)的水溶液进行简单处理来实现的。广泛的胺,包括苯胺和氨基酸衍生物,可与各种芳基碘有效结合,产生高产率的磺胺类药物。
