Abstract: In order to address the existence of resistance to existing pesticides, toxicity and environmental impact issues, developing a novel mechanism of pesticides has become an important scientific and technical personnel responsible pesticide. Chlorantraniliprole is an excellent representative of Ryanicide receptor. The synthetic route are varieties. In recent years , 3-2 chlorine pyridine as raw material is the most ideal results. This paper relates to the three-step reaction is mainly bromination, oxidation, hydrolysis. Oxide part is in two different reactions in different solvents oxidant. According to the results to filter out the best reaction solvent and the best catalyst. The experimental product to determine its structure by NMR.
