A reactive ionic liquid was successfully applied in the homogeneous ruthenium-catalyzed alcohol amination for the first time. Through detailed investigation of the phase behavior and the application of sulfonated ligands, a biphasic system was developed, which fulfils several key points of a sustainable process. This strategy allows, without use of additional volatile organic compounds, a pure product phase to be obtained, enabling the catalyst to be used in repetitive recycling runs. Hence, the productivity of the catalyst was increased fivefold to a cumulative turnover number of more than 2500, which reflects a particularly high catalyst productivity for homogeneous ruthenium-catalyzed alcohol amination.

通过避免有害有机溶剂的催化剂回收，在均相钌催化的醇胺化中实现生产力飞跃

反应性离子液体首次成功地用于均相钌催化的醇胺化反应中。通过详细研究相行为和磺化配体的应用，开发了一种双相系统，该系统满足了可持续过程的几个关键点。该策略允许在不使用额外的挥发性有机化合物的情况下获得纯净的产物相，从而使得该催化剂能够用于重复的循环运行中。因此，催化剂的生产率提高了五倍，达到了超过2500的累计周转数，这反映出对于均相钌催化的醇胺化而言，催化剂的生产率特别高。
