Abstract:A series of α oxo ketene dithioacetals were synthesized from methyl or ethyl acetoacetate with potassium carbonate as the base.Disulfide carbon and different halo hydrocarbon as the material.The addition reactions of these compounds with Reformatsky reagent[ethy(bromozincio)a cetate]were performed and synthesized to form a series of organic active intermediate.
Key words:oxo ketene dithioacetal; reformatsky reagent; addition reaction
