Abstract

The invention relates to a copper complex, particularly a double-terminal-group pyridine copper complex and a preparation method thereof. The invention aims to provide a chiral terminal-group pyridine copper complex applicable to the field of asymmetric catalytic reaction and a preparation method thereof. The chemical formula of the double-terminal-group pyridine copper complex is [(C24H22N4O4)(CuCl4)(H2O)]. The preparation method comprises the following steps: (1) respectively dissolving ligands N,N'-di(3-methylpyridyl)-2,3,5,6-diimido-dicyclo(2,2,2,)-7-octylene and cupric chloride in a mole ratio of 1:(1-1.2) in dichloromethane to form a ligand solution, dissolving cupric chloride in ethanol to form a cupric chloride ethanol solution, and adding dilute hydrochloric acid with the isometric concentration of 0.01M into the cupric chloride ethanol solution to prepare a salt solution; and (2) at room temperature, putting the ligand solution to the lower layer of a container, putting the salt solution on the ligand solution, standing in the stratified state until yellow block crystals precipitate, filtering, and collecting the double-terminal-group pyridine copper complex.

Description

technical field [0001] The invention relates to a copper complex, in particular to a double-terminal pyridine copper complex and a preparation method thereof. Background technique [0002] Transition metal complexes have broad application prospects in the fields of catalysis, luminescence, and biomedicine due to their optical, electrical, and magnetic properties. development research. The synthesis of chiral complexes also has a very important impact on the development of other industries. N,N'-bis(3-methylpyridine)-2,3,5,6-diimide-bicyclo(2,2,2,)-7-octene ligand, due to its semi-rigid Ligands will exhibit different configurations and have rich coordination modes. The ligand and copper chloride generate a chiral complex under the action of dilute hydrochloric acid, which has not been reported yet. Contents of the invention [0003] The present invention aims at the above current situation, and provides a chiral terminal pyridine copper complex and a preparation method ...
