[Chemical Properties]

This product is liquid, bp30 ℃, volatile at room temperature, soluble in inert organic solvent, and decomposes in contact with water.
[Uses]

Trifluoromethyl sulfinyl chloride is an intermediate for the insecticide fipronil.
[Synthesis]

The preparation method of Trifluoromethyl sulfinyl chloride is that CF3Cl is reacted with sodium dithionite to generate sodium trifluoromethyl sulfite, and then reacted with thionyl chloride to generate a product. Reaction equation: CF3Cl1+Na2S2O4→CF3SO2Na[SOCl2]→CF3SOCl
It can also be reacted with potassium trifluoroacetate and sulfur dioxide in a solvent to generate Potassium trifluoromethyl sulfoxide, and then react with thionyl chloride to produce the product. Reaction equation: CF3COOK+SO2→CF3SO2K→CF3< /SUB>SOCl
