Different combinations of metallic nitrates and bromides were used as redox mediators in the conversion of sulfides to
sulfoxides. The metal salts were used in catalytic amounts in the oxidation reaction. It is suggested that in the oxidation and
oxygenation processes are involved species originated from the nitrate/nitrite redox cycles and/or the dissolved atmospheric
dioxygen and/or coordinated water molecules, all in combination with the redox couple 2Br.Br2 + 2e.. The utilized
metallic centers showed distinct reactivity; Fe
