Ionic transformations in extremely nonpolar fluorous media: phase transfer catalysis of halide substitution reactions.
Fluorous solutions of alkyl halides Rf8(CH2)mX (m = 2, 3; X = Cl, Br, I) are inert toward solid or aqueous NaCl, NaBr, and KI, but halide substitution occurs in the presence of fluorous phosphonium salts (10 mol %, 76-100 degrees C).
