Preparation method of 2-substitured phenoxy-6-pyridine formyl chloride and preparation method for picolinafen

The invention provides a preparation method of 2-substitured phenoxy-6-pyridine formyl chloride and a preparation method for picolinafen. Bis(trichloromethyl) carbonic ester(triphosgene) is used as achloride agent for performing a chloroformylation reaction of 2-(3-trifluoromethylphenoxy)-6-pyridine carboxylic acid. The method is mild in synthesis condition, safe, easy to control an operating process, simple and convenient in post-processing, little in wastewater quantity, and environmentally friendly, and capable of avoiding using corrosive reactants of thionyl chloride and the like, reducing the emission of pollution gases of sulfur dioxide and hydrogen chloride and the like and the emission of wastewater, reducing the requirements to a device, and simplifying the operation, the preparation method is beneficial to improve a preparation method of a picolinafen herbicide, and has the extensive application prospect.
