Abstract

The invention discloses a copper-containing coordination polymer based on asymmetric indoledicarboxylic acid, and relates to the field of chemical materials and medicines. The prepared copper-containing coordination polymer of asymmetric indoledicarboxylic acid is mainly prepared from an asymmetric indoledicarboxylic acid ligand and a copper salt, benzyl alcohol or a derivative thereof and aniline are used as reaction raw materials in synthesis of a substituted amine compound, and strong acid and toxic halogenated hydrocarbon are replaced as raw materials; the conditions for synthesizing substituted amine compounds are mild, and the polymer can be recycled as a catalyst, has general tolerance to benzyl alcohol derivatives, and is an environment-friendly catalyst. The invention also discloses a preparation method of the copper-containing coordination polymer based on asymmetric indoledicarboxylic acid, and the preparation method is simple to operate.

Description

technical field [0001] The invention relates to the fields of chemical materials and medicines, in particular to a copper-containing coordination polymer based on asymmetric indole dicarboxylic acid, its preparation method and application. Background technique [0002] The carbon-alkylation reaction of alcohols with amines adopts a hydrogen-borrowing or hydrogen-autotransfer strategy, and is of great significance due to its wide application in materials science and the pharmaceutical industry. Therefore, the synthesis of substituted amines has attracted a lot of attention in medicine, agriculture and The broad interests and concerns of scientists in the field of materials. [0003] At the same time, with the rise of the development concept of green chemistry, it is imminent to seek a green economy, environmental protection and environment-friendly catalyst to synthesize amine compounds. Due to catalyst-product separation and recycling issues, heterogeneous catalysts are dev...
