| titleOfInvention | A kind of preparation method of 2-(5-fluoro-2,4-dinitrophenoxy) acetate |
| abstract | The invention belongs to the technical field of organic synthesis, and in particular relates to a preparation method of 2-(5-fluoro-2,4-dinitrophenoxy) acetate, comprising the following steps: Step 1, using 2,4-difluoroacetate Nitrobenzene is used as a raw material, and 5-fluoro-2,4-dinitrophenol is generated by hydrolysis under the catalysis of alkali; in step 2, 5-fluoro-2,4-dinitrophenol and ethyl chloroacetate are used as additives Then, catalyst A and catalyst B are added, and a nucleophilic substitution reaction occurs to obtain 2-(5-fluoro-2,4-dinitrophenoxy) acetate; the preparation method of the present invention has high yield, simple reaction and easy operation, with the significant advantage of low production costs. |
