Abstract:The methods for synthesis of sulfentrazone and its key intermediates were reviewed. The synthetic methods for sulfentrazone can be concluded to sulfonyl chloride, sulfonic acid, sulfonate, sulfonamide and some other methods. Among them, the sulfonyl chloride method is the earliest classic method for the preparation of sulfentrazone. The sulfonamide method, especially the route from the key intermediate 5a and sulfonamide under copper-containing catalyst conditions may become a new alternative due to its prominent features such as starting materials easily obtained, easy industrialization operation and the high yield, as well as effectively avoiding the nitrification process and the large amounts of waste acid and waste water during the process.
Key words:sulfentrazone; herbicide; protoporphyrinogen oxidase inhibitor(PPOI); synthetic method
