Dperoxovanadates

Dperoxovanadates are a class of inorganic compounds containing the dperoxovanadate anion, which has the formula [VO(O2)2]2-. These compounds are derived from vanadium and peroxide, and are often synthesized in aqueous solutions. The dperoxovanadate anion is characterized by a central vanadium atom bonded to one oxide ligand and two peroxide ligands. The peroxide ligands act as bidentate ligands, chelating to the vanadium center. The overall charge of the anion is -2. These compounds are typically stable in alkaline or neutral solutions but can decompose in acidic conditions, releasing oxygen. Dperoxovanadates are known for their oxidative properties, which makes them of interest in catalysis and as oxidizing agents in various chemical reactions. Their synthesis often involves the reaction of a vanadium(V) salt, such as sodium metavanadate, with hydrogen peroxide in the presence of a base. The precise structure and stability of dperoxovanadates can be influenced by the counterions present and the specific reaction conditions. Research has explored their applications in areas such as the epoxidation of olefins and other oxidation processes.
