Chlorfenprox

Preparation method: Preparation of tert-butyl chloride: It is prepared by reacting tert-butanol with hydrochloric acid, mixing and shaking for 20 minutes. Preparation of 2-(4-chlorophenyl)-2-methylpropane In the mixture of chlorobenzene and anhydrous iron trichloride, pass dry hydrogen chloride, add tert-butyl chloride dropwise at 30°C, and finish it all by drop. Continue the reaction for 2h. Preparation of 2-(4-chlorophenyl)-2-chloromethylpropane The product of the previous step was reacted with thionyl chloride at 100°C for 2h in the presence of the catalyst benzoyl peroxide. Synthesis of Permethrin The product of the previous step was mixed with m-phenoxybenzyl alcohol and sodium hydroxide, and nitrogen was passed through the solvent, and the reaction was stirred at 120°C for 8h.
