摘要

新型催化剂的开发是现代化学的一个重要课题。本文设计并合成了一种钌配合物，该配合物带有功能配体[（对伞花烃）Ru(2-OH-6-BzlmHpy)Cl][Cl]。在催化剂（0.2 摩尔%）和KOH（1.5摩尔%）存在下，在150 °C的纯水中，24 h，甘油选择性转化为乳酸钾，产率为>；99 %，选择性为>；99 %。发现配体中的OH官能团对钌配合物的催化活性至关重要。此外，还进行了DFT计算和力学实验

Selective conversion of glycerol to potassium lactate and hydrogen gas in water catalyzed by a ruthenium complex bearing a functional ligand [(p-cymene)Ru(2-OH-6-BzlmHpy)Cl][Cl]

The development of new-type of catalysts is an important topic for modern chemistry. Herein, a ruthenium complex bearing a functional ligand [(p-cymene)Ru(2-OH-6-BzlmHpy)Cl][Cl] was designed and synthesized. In the presence of catalyst (0.2 mol %) and KOH (1.5 equiv), the selective conversion of glycerol to potassium lactate was carried out at 150 °C in pure water for 24 h to afford potassium lactate in >99 % yield with >99 % selectivity. OH functional group in the ligand was found to be crucially important for catalytic activity of ruthenium complex. Furthermore, DFT calculations and mechanistic experiments were presented

期刊介绍： The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes. The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods. The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
