Problems solved by technology

In addition, if the reaction is carried out in a heterogeneous phase, the separation and purification of the substrate will become easier. For this reason, the traditional method is to immobilize the catalyst, and the metal-organic complex is stable, as a heterogeneous reaction Catalyst has great potential

Abstract

The invention discloses a copper complex, a preparation method and application thereof. The chemical formula of the copper complex is [Cu(dpca)(phen)(CH3OH)]NO3.H2O, Hdpca is 2,4-dihydroxy pyrimidine-5-carboxylic acid, and phen is phenanthroline. A monocrystal complex by self assembling of molecules has certain granularity, a unique structure, high catalytic activity, high selectivity and good stability, is mild in condition, high in yield, good in reproducibility and free of pollution in production, can be prepared at normal temperature and normal pressure, and has latent economic benefit, social benefit and environmental benefit.

Description

technical field [0001] The invention belongs to the technical field of metal-organic complex materials, and in particular relates to a copper complex with high catalytic activity constructed by pyrimidine carboxylic acid ligands and a preparation method thereof. Background technique [0002] The synthesis of metal-organic complexes by purposefully designing ligands and selecting metal ions has become one of the research hotspots in coordination chemistry. This is not only due to the rich and colorful structures of organo-metal complexes, but more importantly, they exhibit superior properties in many fields, such as optics, magnetism, adsorption and separation, catalysis, and biological activity. The structure of the complex is affected by many factors, so it is difficult to predict the structure. Therefore, it is of great significance to systematically study the structure and properties of the complex by designing and selecting appropriate ligands and metal ions and controll...
