Problems solved by technology
Traditional oxidation methods mostly use oxidants such as chromate, permanganate, and organic peracids, which have low atomic utilization and large discharge of three wastes. Some processes even cause harm to the human body and seriously pollute the environment.

Caged ruthenium metal-organic complex crystals and preparation methods thereof relate to metal complex crystals and preparation methods thereof. The two metal-organic complexes in the present invention all use RuCl2(PPh3)3 as metal precursors. Types of organic ligands were prepared, and then the crystals of the two complexes were obtained by further diffusion culture method. The crystal structures of the two novel metal-organic complexes with cage structure were characterized by X-ray single crystal diffractometer. The results show that these two crystals have clear structure and unique coordination mode, which are very potential catalysts and potential anti-tumor drugs. The study of its catalytic effect found that this kind of complex exhibited mild reaction conditions, simple post-treatment, high catalytic activity and high selectivity in the catalytic alcohol oxidation reaction. Two novel caged ruthenium metal organic complexes (RuCl)4(PPh3)4 of the present invention have the application of catalytic oxidation reaction.
Description
technical field [0001] The invention relates to a metal complex crystal and a preparation method thereof, in particular to a caged ruthenium metal organic complex crystal and a preparation method thereof. Background technique [0002] The research on ruthenium metal complexes has developed rapidly and has broad application prospects. Since the transition metal ruthenium has multiple layers of electrons and unfilled d orbitals, the metal center can not only provide electrons to the ligand, but also accept electrons from the ligand, which can reversibly change the oxidation state and coordination of the metal. Therefore, transition metal ruthenium complexes have been widely used in various catalytic reactions and are one of the hot spots in the field of catalyst research. At present, there are many kinds of ruthenium metal-organic complexes, especially aromatic hydrocarbon ruthenium complexes, which are widely used in catalytic hydrogenation reaction, hydrogenation transfer r...
