The Chinese Academy of Sciences' Guangzhou Institute of Biomedicine and Health Jiang Qi experimental group made new progress in the research of substituted divinyl ether synthesis. The relevant results were on the 18th of September in the “Science Reportâ€, a comprehensive academic journal under the Natural Publishing Group. Published (Sci. Rep. 5, 14231 (2015); DOI: 10.1038/srep14231).
The substituted divinyl ether is the key structure of the vinyl polymer material. The material containing this structure is biodegradable and belongs to the environment-friendly material. It has important significance and application value, but its synthesis is very difficult. The previous synthesis conditions All of them are very demanding. Therefore, it is very challenging to easily and efficiently synthesize compounds having a substituted divinyl ether structure.
In the study, Jiang Hao's group found that epichlorohydrin in the two-phase reaction solution of inorganic alkali aqueous solution and organic solvent, adding a catalytic amount of phase transfer catalyst can be polymerized to form a substituted divinyl ether structural unit, and all raw materials used in the reaction. Easy to get, low cost. This reaction is a brand-new type of reaction with a completely new reaction mechanism. It has not been reported in the existing literature and has important historical significance in organic chemistry. In addition, the products obtained by the reaction not only have nucleophilicity but also have electrophilicity, and thus can be conveniently used to prepare monomers that are biodegradable and environment-friendly materials. The research group initially demonstrated this feasibility in further studies. . At present, the research group is conducting more in-depth research and exploration.
The study was funded by the National Natural Science Foundation of China (21,472,191).
