Abstract

In this contribution, a new POM-based ionic liquid, namely (P_6,6,6,14)₄[W₁₀O₃₂], was fully characterized. Its viscosity and its very low dielectric constant make this hybrid ionic liquid suitable to be used as a solvent for organic transformations. As a proof of concept, this unique ionic liquid having both solvent and catalyst properties was tested for the catalytic oxidation of various alcohols and alkenes in the presence of H₂O₂.
