| titleOfInvention | A kind of method for preparing carboxyphenylboronic acid |
| abstract | The invention discloses a method for preparing carboxyphenylboronic acid. Starting from halogenated phenylboronic acid, a trimer is formed after being heated and refluxed in a solvent for dehydration, and then the trimer forms a corresponding trimer with metal magnesium or isopropylmagnesium chloride. solid Grignard reagent, and then pass carbon dioxide gas or add dry ice to react at low temperature. After the reaction, hydrochloric acid was added to adjust to pH=2-3 for hydrolysis, and carboxyphenylboronic acid was precipitated, and the pure product was obtained after filtration and drying. This method can achieve good yields for o-, m-, and p-carboxyphenylboronic acids. The reagents used are simple, the operation is convenient, and the generation of a large amount of solid waste is avoided. |
