Abstract
Fluthiacet-methyl belongs to heterocyclic compounds,its synthesis process is very difficult,especially preparing its intermediate because of excessive reaction steps,complex mechanism and the demand to strictly control isomers formation,so it is a very important to select reasonable and practical process route.2-Fluoro-4-chloro-5-methoxy carbonyl methylthio phenyl isothiocyanate is a very important intermediate in synthesis of fluthiacet-methyl.In this paper,the rationality of synthesizing 2-fluoro-4-chloro-5-methoxy carbonyl methylthio phenyl isothiocyanate by the nitrification process was discussed.
