introduction | 2-fluorobenzonitrile, also called o-fluorobenzonitrile, is an organic aromatic fluoride. Organic aromatic fluoride is an important raw material and intermediate for the preparation of fluorine-containing physiologically active substances, and has a wide range of applications in medicine, pesticides, dyes, etc. In terms of medicine, fluorine-containing compounds have the characteristics of less dosage, strong selectivity, and high efficacy compared with other compounds; in terms of dyes, after the introduction of fluorine atoms, the dye has the advantages of bright color and not easy to fade. |
preparation method | 6.88g(50mmol) o-chlorobenzonitrile, 11.6g(200mmol)KF,20ml sulfolane, 2.1g(5mmol) tetraphenylphosphorus bromide are sequentially added into a microwave reactor, heated at 300W power, GC tracks the reaction, ends the reaction when the raw material content is less than 5%, and stops the reaction after reacting at 180 ℃ for 4 hours under microwave action, the reaction liquid is cooled to room temperature, the insoluble solid is filtered by vacuum extraction, and the filtrate is distilled under vacuum to obtain 4.56g of 2-fluorobenzonitrile, and the final yield is 74.6%. |
uses | 2-fluorobenzonitrile is an organic synthesis intermediate and a pharmaceutical intermediate, mainly used in laboratory research and development and chemical and pharmaceutical synthesis. |
