carboxylic acids is a very green, efficient and sustainable method for the production of (bio-based) amines. However, with current technology, this reaction requires two to three reaction steps. Here, we report the first (heterogeneous) catalytic system for the one-pot reductive amination of carboxylic acids to amines, with solely H2 and NH3 as the reactants. This reaction can be performed with relatively cheap
羧酸的还原胺化是一种非常绿色,高效和可持续的生产(生物基)胺的方法。但是,使用当前技术,该反应需要两到三个反应步骤。在这里,我们报道了第一个(非均相)催化体系,用于仅用H 2和NH 3作反应物将羧酸单胺还原胺化。该反应可以使用相对便宜的钌-钨双金属催化剂在绿色和良性溶剂环戊基甲基醚(CPME)中进行。在高转化率下,伯胺的选择性可达99%。另外,该催化剂是可回收的并且对常见杂质如水和阳离子(例如羧酸钠)具有耐受性。
