A kind of copper-containing complex catalyst and its preparation method and application

Abstract

The invention relates to a copper-containing complex catalyst and a preparation method and application thereof. The preparation method comprises the following steps: adding water into copper carbonate, dripping perchloric acid to generate reaction, evaporating a blue solution after reaction is completed so as to be concentrated to obtain crystals, and finally obtaining copperperchlorate hydrate; adding the copperperchlorate hydrate and organic diamine into a solvent, stirring, performing heating backflow reaction under the temperature of 50-80 DEG C for 5-8 hours, and performing filtering, washing and drying to obtain a product. Compared with the prior art, the preparation method for the catalyst is simpler, and the catalysis activity is relatively high; pollution cannot be generated.

Background technique

[0002] Transition metal-catalyzed C-H functionalization reaction is an important intermediate process for the construction of new C-C, C-N and C-O chemical bonds, and is an effective method for preparing multifunctional substituted organic compounds. Traditional catalysts for C-H bond activation reactions mainly include transition metal complexes such as ruthenium, rhodium, and palladium. . In order to solve the above problems and continuously develop new and more efficient C-H functionalization reactions, chemists have gradually paid attention to copper complexes with lower prices in recent years. It should...
