A process method for producing a pesticide by using carbon dioxide includes: weighing a 1,3-cyclohexanedione substrate 1(a-e), a catalyst and Cs.sub.2CO.sub.3 in a Schlenk bottle, degassing, and continuously introducing 1 atm of carbon dioxide; adding a solvent and reacting for 48 h in an oil bath at 50° C. After the reaction was completed, post-treatment was carried out to obtain a 2-carboxyl-1,3-cyclohexanedione compound 2(a-e). The obtained acid is acylated and then added dropwise to a dichloromethane solution containing aniline to react for 2 h at room temperature. After the reaction, column chromatography was performed to obtain a pesticide compound 3(a-e). Adding the pesticide compound 3(a-e) into 50% concentrated sulfuric acid and refluxing at 80° C. for 8 hours. Through separation, a pesticide product compound 4(a-e) was obtained. The process method is simple, with low requirements on equipment, wide sources of raw materials, low cost, low toxicity and easy industrial scale-up production.
