TRIFLUOROMETHYL SULFINYL CHLORIDE - 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
