  稳定且可重复使用的纳米级Fe 2 O 3催化好氧氧化工艺，用于选择性合成腈和伯酰胺

  摘要：

  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。

These protocols involved economical methods to synthesize value-added aryl nitriles from simple and inexpensive raw materials. Further diversification of the

  在这里，我们使用丙二腈或 AMBN 作为氰化剂，开发了有效且实用的方案，用于在有氧条件下，对在邻位带有硝基和甲氧基取代基的芳基羧酸以及杂芳族羧酸进行 Cu 介导的脱羧氰化反应。这些协议涉及从简单且廉价的原材料合成增值芳基腈的经济方法。对 2-硝基苯腈产品进行了进一步的多样化, 以突出协议的实用性。

  straightforward method for the electrochemical C−H cyanation of arenes and heteroarenes that proceeds at room temperature in MeOH, with NaCN as the reagent in a simple, open, undivided electrochemical cell is reported. The platinum electrodes are passivated by adsorbed cyanide, which allows conversion of an exceptionally broad range of electron‐rich substrates all the way down to dialkyl arenes. The cyanide electrolyte

  据报道，芳烃和杂芳烃的CH-H氰化的直接方法是在室温下于MeOH中进行，NaCN作为试剂在简单，开放，不分隔的电化学池中进行。铂电极被吸附的氰化物钝化，从而可以将范围广泛的富电子底物一直转化为二烷基芳烃。氰化物电解质可以补充HCN，为无盐工业CH氰化打开了机会。
