| 摘 要： | A clean process with 3 steps for the synthesis of FIuthiacet-methyl as a super ettective nerbicide is developed. The product was prepared in several patented methods. However, those methods had the disadvantages of using hazardous materials such as thiophosgene, chloroformate, hexahydropyridazine and phosgene. In the present work, the hazardous materials were replaced by safe reagents, for example,thiophosgene by carbon disulfide, chloroformate and phosgene by his (trichloromethyl) carbonate (BTC) and hexahydropyridazine by hexahydropridazine hydrochloride. Therefore, the process is operationally convenient and safe with little environmental hazard. Furthermore, the total yield (63%) is quite higher than that (39%) reported in literature. The clean process is valuable for manufacturing Fluthiacet methyl in industrial scale.
