Abstract

The monohydration of SO₂ has been achieved in solution mediated by a platinum-aquo complex. Benzamidate ligands play a key role along the process, acting as versatile proton shuttles. Finally, the platinum center allows the stabilization of benzimidic acid and a hydrogensulphite anion, the disfavored tautomers of benzamide and sulphonate, respectively.
