Abstract: The reaction of quercetin with HAuCl₄ in a DMSO–water medium yields the oxidation products of the organic substrate along with the (Me₂S)AuCl complex. According to quantum chemical modeling, the driving force of the process is the transfer of the oxygen atom from the initially formed complex (Me₂SO)AuCl to the organic substrate.

Keywords: quercetin, oxidation, gold complexes, dimethyl sulfoxide, dimethyl sulfide, DFT, modeling.
