The effect of the lipophilicity and coordinating ability of neutral ligands, belonging to the classes of phosphoric amides and pyridine oxides, on the extraction of the neutral oxidants molybdenum (VI)-peroxo complexes from an aqueous acidic phase to an organic one, has been studied. The nature of the Mo (VI)-peroxo species present both in aqueous and organic phase has also been investigated. Sizable amounts of mineral acid, added to ...
