Abstract

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 V_x O_y skeleton or a terminal V-O bond.

Keywords: doubly-charged anions; ion-molecule reactions; mass spectrometry; sulfur dioxide; vanadium.
