| titleOfInvention | One prepares the method for 2,2-dimethylvinylsiloxy ylboronic acid |
| abstract | The invention belongs to chemical technology field.One prepares 2, the method of 2-dimethylvinylsiloxy ylboronic acid, is characterized in that: with an organic solvent 1, under 10 ~ 60 DEG C of conditions, use 3,3-dimethacrylate, reacts 3 ~ 4h with bromine, and reaction terminates rear use alkali and adjusts PH to 9 ~ 10,2 ~ 3h is reacted under 30 ~ 60 DEG C of conditions, reaction terminates rear stratification, and organic layer distillation obtains 2,2-dimethyl ethenyl bromine.With an organic solvent 2, under-78 ~-40 DEG C of temperature condition, use 2,2-dimethyl ethenyl bromine, reacts 2 ~ 3h under metallic lithium and borating agent effect, uses hydrochloric acid to adjust PH to 3 ~ 4, make to be extracted with ethyl acetate, concentration of organic layers filters through the making beating of non-polar hydrocarbon kind solvent, and drying obtains 2,2-dimethylvinylsiloxy ylboronic acid.The present invention has safety and environmental protection, and easy-operating feature, is suitable for suitability for industrialized production. |
