Air Oxidation of HS- Catalyzed by An Mixed-Valence Diruthenium Complex, an Near-IR Probe for HS- Detection
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.
