Vanadium Hydroxide Cluster Ions in the Gas Phase: Bond-Forming Reactions of Doubly-Charged Negative Ions by SO2-Promoted V−O Activation

Vanadium Hydroxide Cluster Ions in the Gas Phase: Bond-Forming Reactions of Doubly-Charged Negative Ions by SO2-Promoted V−O Activation

The gas-phase reactivity of doubly-charged vanadium hydroxides anions with SO2 has been studied by experimental and computational methods. The obtained results highlight the role of sulfur dioxide in promoting unprecedented bond-forming reactions, which produce singly-charged products by breaking the VxOy skeleton or a terminal V−O bond. Two charges are better than one: Doubly-charged vanadium hydroxide anions undergo chemical reactions with sulfur dioxide, which promotes the breakage and formation of V−O chemical bonds. They behave as effective VO3− and HO− donors to SO2, producing singly-charged ions.
