Abstract
Useful processes for isolating the fluorinated products formed by reaction with 4-tert-butyl-2,6-dimethylphenylsulfur trifluoride (Fluolead) are disclosed. The processes comprise the conversion of the byproduct (formula I) to sulfinate ester (formula V), and to sulfonate eater (formula VI), and then to the water-soluble sulfonate salt (formula IV) in the presence of the fluorinated products.
