| Abstract: | [Aims] A industrialized synthetic route of dithiopyr was developed to break foreign technology monopoly.[Methods] Dithiopyr was synthesized using ethyl trifluoroacetoacetate and isovaleraldehyde as raw materials by the reaction of cydization,dehydration,defluorination,hydrolysis,acylation and condesation.[Results] The total yield was 60%,and the purity was 97%.[Conclusions] This synthetic route can be used in industrialized production. |
