nitriles and amides from easily available starting materials using cost-effective catalysts and green reagents is highly desired. In this regard, herein we report the nanoscale iron oxide-catalyzed environmentally benign synthesis of nitriles and primary amides from aldehydes and aqueous ammonia in the presence of 1 bar O2 or air. Under mild reaction conditions, this iron-catalyzed aerobic oxidation process
在腈纶或酰胺基团形式的功能化分子中可持续引入氮基是至关重要的,因为在许多生命科学分子,天然产物和材料中都发现了含氮基序。因此,非常需要使用具有成本效益的催化剂和绿色试剂从容易获得的起始原料合成腈和酰胺的方法。就这一点而言,本文报道了在1 bar O 2的存在下,由醛和氨水进行的纳米级氧化铁催化的腈和伯酰胺的环境友好合成。或空气。在温和的反应条件下,该铁催化的需氧氧化过程继续进行,以合成功能化且结构多样的芳族,脂族和杂环腈。另外,应用该铁基方案,还已经在水介质中制备了伯酰胺。
