| titleOfInvention | A kind of preparation method of methyl 2,2-difluoropiperate |
| abstract | <b/>The present invention relates to the field of organic synthesis, in particular to a method for preparing methyl 2,2-difluoropiperate. The invention provides a method for preparing methyl 2,2-difluoropiperate, which comprises the following steps: react 2,2-difluoropiperoyl fluoride (II) with methanol, and prepare 2,2-difluoropiperonyl fluoride (II) through esterification Methyl difluoropiperate (III), the reaction equation is as follows: . The main advantages of the present invention are as follows: the synthetic route of the preparation method of methyl 2,2-difluoropiperate provided by the present invention is short, the technical process is easy to control, the reaction is complete, the yield is high, and the prepared target product has high purity, The quality is stable and fully meets the requirements for use as pesticides or pharmaceutical intermediates. In addition, the raw materials and reagents used in this method are cheap, the amount of solvent used in each step of the reaction is small, and there is less waste liquid, which not only reduces costs and environmental pollution, but is also very convenient. Large-scale commercial production. |
