Abstract: The strongly near-IR-active mixed-valence diruthenium complex [Ru2TIEDCl4]Cl, where TIED = tetraiminoethylenedimacrocycle, was found to be a highly active catalyst for air oxidation of HS– forming polysulfide species and H2O2. The reaction provides a convenient method for the detection of the HS– generation rate of a H2S donor of medical importance.
