The addition of functionalized arylmagnesium halides to nitroarenes in THF (-20 degrees C, 2 h) provides, after reductive workup (FeCl(2), NaBH(4)), various polyfunctional diarylamines in 63-86% yield. Heterocyclic arylated amines can be prepared by this one-pot procedure. A mechanistic rationale of this reaction is given.
在 THF 中向硝基
芳烃添加官能化芳基
镁卤化物(-20 摄氏度,2 小时),在还原处理后(FeCl(2)、NaBH(4)),各种多功能二芳基胺的产率为 63-86%。杂环芳基化胺可以通过这种一锅法制备。给出了该反应的机械原理。
