Paragraph 0037; 0038; 0039; 0040, (2018/10/19)
The invention discloses a method for preparing clothianidin. The response equation is shown in the description, wherein R is selected from C1-C6 alkyl, benzyl, phenethyl and phenylpropyl; an oxidationreagent is selected from hydrogen peroxide, hydrogen peroxide-oxygen and ozone; a catalyst is selected from sodium hydroxide, potassium hydroxide, formic acid, acetic acid, hydrochloric acid and sulfuric acid. A compound I shown in the response equation is oxidized by the oxidation reagent in suitable solvent under the effect of the catalyst to prepare into the clothianidin. According to the method, the clothianidin is prepared with the method for oxidizing the compound I with the oxidation reagent, the production cost is reduced, reaction conditions are mild, the atom utilization rate is high, brine waste is avoided, and a post-processing method is simple and easy to carry out, economical and effective, and is capable of easily achieving industrial production.
