The Synthesis Study on Kresoxim-methyl |
LIU Wei dong etc.(Hunan Research Institute of Chemical Industry; Changsha; 410007; China) |
Abstract:Kresoxim methyl was prepared by reacting the intermediate, methyl 2 (2 methylphenoxymethyl) phenylglyoxylate, with O-methylhydroxylamine hydrochloride. The resulting E/Z isomer mixture was treated with hydrochloride for substantial rearrangement of the Z to the E isomer. The intermediate was synthesized by using O cresol, phthalide, thionyl chloride, and sodium cyanide as raw materials. The total yield of the five steps reaches 57.2% (according to phthalide), and the process is convinient and suitable f... |
Key words:Kresoxim-methyl; O cresol; phthalide; synthesis |
