There are several methods for fluorinating organic compounds
There are several methods for fluorination of organic compounds, including selective fluorination. Fluorides of alkali metals or fluorides of antimony, mercury, and silver can be used to convert halogenated alkanes or sulfonic acid esters into fluorinated alkanes. The reaction is generally carried out in an anhydrous polar medium; Antimony pentachloride can also be used as a catalyst for fluorinat
