Summary:

Perfluorinated quaternary ammonium cations, [CF₃(CF₂)₇(CH₂)₃]₃CH₃N⁺ (RFN⁺), were synthesized and used as counter cations for the [WZnM₂(H₂O)₂(ZnW₉O₃₄)₂]¹²⁻ (M = Mn(II), Zn(II)), polyoxometalate. The (RFN⁺)₁₂[WZnM₂(H₂O)₂(ZnW9O₃₄)₂] compounds were fluorous biphasic catalysts for alcohol and alkenol oxidation, and alkene epoxidation with aqueous hydrogen peroxide. Reaction protocols with or without a fluorous solvent were tested. The catalytic activity and selectivity was affected both by the hydrophobicity of the solvent and the substrate.
