The invention relates to a process for synthesizing triketone herbicide cyclic sulcotrione. The method comprises the following steps: (1) synthesizing 2-chloro-6-methylsulfonyl methylbenzene; (2) synthesizing 2-chloro-3-acetyl-6-methylsulfonyl methylbenzene; (3) synthesizing 2-chloro-3-methyl-4-methylsulfonyl benzoic acid; (4) synthesizing methyl 2-chloro-3-methyl-4-methylsulfonyl benzoate; (5) synthesizing methyl 2-chloro-3-bromomethyl-4-methylsulfonyl benzoate; (6) synthesizing 2-chloro-3-(2,2,2-trifluoroethyoxy)methyl-4-methylsulfonyl benzoic acid; (7) synthesizing 2-chloro-3-(2,2,2-trifluoroethyoxy)methyl-4-methylsulfonyl benzoic acid 3-oxo-1-cyclohexene ester; and (8) synthesizing cyclic sulcotrione. The process disclosed by the invention has the beneficial effects that the reaction steps are reduced, the reaction time is shortened, and the yield of intermediates is improved; the reaction conditions are mild and safe; and the cost is reduced.
