Abstract

The invention discloses 2-ferrocenyl-arylquinoline which has the general formula shown in the specification, wherein Aryl is the aryl and is connected to the position 5, 6, 7 or 8 of quinoline. A preparation method of 2-ferrocenyl-arylquinoline comprises the following steps: adding acetylferrocene, bromo-o-hydroxyl methyl aniline, Aryl-B(OH)2, [Ir(cod)Cl]2, palladium salt, triphenylphosphine and alkali into the organic solvent, heating and refluxing for reacting under inert gas shielding, and separating and purifying to obtain the product after the reaction is ended. The provided 2-ferrocenyl-arylquinoline compound has the dual characteristics of ferrocene and arylquinoline and can be applied to the fields of electrochemistry, biochemistry, materials chemistry and organocatalysis.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a class of 2-ferrocenyl-arylquinoline compounds, and also relates to a preparation method of the compounds. Background technique [0002] Quinoline and its derivatives have biological and pharmacological activities such as sterilization, antibacterial, antiallergic, and antitumor, and are widely used in medicine, pesticide production, and functional materials. Quinoline derivatives were first extracted from coal tar. The technical route is complex and the product types are limited. Some important quinoline derivatives cannot be obtained by this method. [0003] In recent years, on the basis of traditional synthetic routes, technicians have developed a new synthetic route using transition metal complexes as catalysts, which is currently the most researched and most promising method. For example, Au can catalyze the three-component coupling reaction of aldehydes, ami...
