No muss, no fuss: A rhodium‐catalyzed direct intermolecular CH amination of benzamides and ketoximes using aryl azides as the amine source has been developed. The reaction exhibits a broad substrate scope with excellent functional‐group tolerance, requires no external oxidants, releases N2 as the only by‐product, and produces diarylamines in high yields.
勿乱,勿扰:已开发出使用芳基叠氮化物作为胺源的铑催化的苯甲酰胺和酮肟的分子间CH胺化反应。该反应具有广泛的底物范围,具有出色的官能团耐受性,不需要外部氧化剂,释放N 2作为唯一的副产物,并以高收率生产二芳基胺。
