may permit solving challenges of chemical synthesis. We report here on a catalytic C−N bond formation reaction—the reductive alkylation of nitriles. Aldehydes or ketones and nitriles, all abundantly available and low‐cost starting materials, undergo a reductive coupling to form secondary alkylamines and inexpensive hydrogen is used as the reducing agent. The reaction has a very broad scope and many functional
由于它们在生物学和化学中的重要性,因此非常需要开发CN键形成反应。3d金属催化的最新进展表明,独特的选择性模式可以解决化学合成难题。我们在这里报告催化性C-N键形成反应-腈的还原烷基化。醛,酮和腈都是可得的廉价原料,它们经过还原偶合形成仲烷基胺,廉价的氢用作还原剂。该反应的范围非常广泛,并且可以耐受许多官能团,包括对氢化敏感的实例。我们开发了一种新型的钴催化剂,该催化剂具有纳米结构,可重复使用且易于处理。
