Synthesis method of oxyfluorfen

The invention relates to a synthesis method of oxyfluorfen, which comprises the following steps: (1) reacting 3,4-dichlorobenzotrifluoride, potassium hydroxide and tert-butyl alcohol in a molar ratioof (1-1.5): (3-5): (2-4), dechlorinating in a polar solvent to obtain a mixed solution containing 2-chloro-4-trifluoromethylphenol potassium, cooling, carrying out suction filtration, and carrying outreduced pressure treatment on the mixed solution; (2) adding potassium carbonate to the mixed solution, adding dropwise 2,4-dihalogenated nitrobenzene while heating is performed, with the molar ratioof the potassium carbonate, the 2,4-dihalogenated nitrobenzene and the 3,4-dichlorobenzotrifluoride being (1-1.5): 1: (2-2.3), performing suction filtration after a heat preservation reaction, and adding methylbenzene to dissolve 2,4-bis(2-chloro-4-trifluoromethyl) phenoxy nitrobenzene in the filtrate; and (3) heating the mixed solution to 30 DEG C, then dropwise adding potassium ethylate into the solution, carrying out a heat preservation reaction, with the molar ratio of ethanol, potassium hydroxide and the 2,4-dihalogenated nitrobenzene being 4-5:1.2-1.4:1, and extracting oxyfluorfen fromthe reacted mixed solution. According to the present invention, with the new synthesis method, the synthesis cost of oxyfluorfen is significantly reduced.
