Paragraph 0079-0083, (2021/04/14)
The invention particularly relates to a heterogeneous catalyst Cu@COF-Me-M as well as a preparation method and application thereof. An existing heterogeneous catalyst is low in diffusion speed and high in preparation difficulty. The invention provides a heterogeneous catalyst Cu@COF-Me-M, which is prepared by adding a compound shown in a formula I and triformyl phloroglucinol serving as raw materials into a mesitylene, dimethyl sulfoxide and acetic acid reaction system, heating, reacting, and cooling to room temperature to obtain a covalent organic framework COF-Me-M, and reacting with copper chloride to obtain the Cu@COF-Me-M. the heterogeneous catalyst can effectively catalyze a three-component coupling reaction. The heterogeneous catalyst is simpler in preparation process, low in dosage, high in catalytic efficiency and convenient to recover, and has important significance in industrial production.
