Catalytic reductive reactions are essential for laboratory and industrial-scale organic synthesis. However, the nowadays trend is the development of new, more and more complicated reducing systems, which hinders the application of such highly efficient approaches in practice. Another way to achieve the highly active systems is enhancing the activity of the earlier developed catalysts with simple structures
催化还原反应对于实验室和工业规模的有机合成至关重要。然而,当今的趋势是开发新的、越来越复杂的还原系统,这阻碍了这种高效方法在实践中的应用。实现高活性体系的另一种方法是提高早期开发的具有简单结构的催化剂的活性。在此,我们证明了在向反应混合物中加入碘化物后,钌催化剂在还原胺化中的催化活性显着增加(高达 15 倍)。催化剂周转数高达 9000,产品的制备产率达到了。制定了这种效果的合理原因。
