20621-29-8 - Reference Information
| Use | Trifluoromethyl thionyl chloride is an intermediate of the insecticide fipronil. |
| Production method | The preparation method is to react CF3Cl with sodium dithionite to generate sodium trifluoromethyl sulfite, and then react with thionyl chloride to generate products. Reaction equation: CF3Cl1 Na2S2O4 → CF3SO2Na[SOCl2]→ CF3SOCl can also react with potassium trifluoroacetate and sulfur dioxide in a solvent to form potassium trifluoromethyl thionyl, and then react with thionyl chloride to form a product. Reaction equation: CF3COOK SO2 → CF3SO2K → CF3SOCl |
