Page/Page column 4-6, (2020/12/30)
The invention discloses a synthesis method of oxyfluorfen. The method comprises the following steps: using 3, 4-dichlorobenzotrifluoride and 2, 4-difluoronitrobenzene as initial raw materials, carrying out etherification reaction to obtain a nitro compound, and carrying out alcoholysis reaction on the nitro compound and a potassium hydroxide ethanol solution to synthesize the oxyfluorfen. According to the method, the 3, 4-dichlorobenzotrifluoride and the 2, 4-difluoronitrobenzene are taken as the initial raw materials, the 3, 4-dichlorobenzotrifluoride and the 2, 4-difluoronitrobenzene are synthesized through etherification and alcoholysis reactions, no isomer is generated, recrystallization is not needed, the content of the synthesized product is greater than 97%, and the yield is greaterthan 93%.
