for coupling of anilines, acetophenones, and elemental sulfur to afford N-arylthioglyoxamides has been developed. Reactions proceeded in the presence of Na2SO3 and DMSO, thus eliminating the need for transition metals and external oxidants. Functionalities such as halogen, ester, methylthio, and heterocycle groups were compatible with the conditions. Electron-poor acetophenones sometimes gave isosteric
已经开发了一种简单的方法,用于偶联苯胺、苯乙酮和元素硫以提供N-芳基硫代乙二酰胺。反应在 Na 2 SO 3和 DMSO 的存在下进行,因此无需过渡金属和外部氧化剂。卤素、酯、甲硫基和杂环基团等官能团与条件相容。缺电子苯乙酮有时会产生等排乙二酰胺。
