Heteronuclear NMR experiments, in particular 51 V, wereperformed with the aim to elucidate the nature of vanadates and peroxovanadates in hydrophilic ionic liquids (i.e., [bmim][BF 4 ], [bmim][TfO] and [bdmim][BF 4 ]). The data so far reported clearly indicate that ionic liquids have a strong influence on the solution chemistry of vanadate in water both for the formation of the aggregates (with and without H 2 O 2 ) and for the rate of peroxide consumption catalyzed by vanadium. In BF 4 – containing ionic liquids, formation of vanadate–fluoride adducts is suggested. The obtained results are also discussed in the light of the reactivity data of peroxovanadates in ionic liquids. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
