Paragraph 0043; 0046; 0049; 0052, (2017/08/29)
The invention discloses a preparation method of carbofuran derivatives. The preparation method of the carbofuran derivatives comprises the following steps: (1) taking amine derivatives and sulfur monochloride as raw materials, adding a first acid-binding agent and a reaction solvent and performing sulfuration reaction to obtain a first intermediate disulfide, wherein the first acid-binding agent is triethylamine and the reaction solvent is chloroform or dichloromethane; (2) performing chlorination reaction on the first intermediate disulfide and chlorine which serve as raw materials to obtain a second intermediate nitrogen and sulfur chloride; (3) taking the second intermediate nitrogen and sulfur chloride and carbofuran as raw materials, adding a second acid-binding agent and performing condensation reaction to obtain the carbofuran derivatives. The preparation method has the advantages that the process is simple, and the product is low in toxicity, high in purity and high in yield.
