Abstract

The strongly near-IR-active mixed-valence diruthenium complex [Ru(2)TIEDCl(4)]Cl, where TIED = tetraiminoethylenedimacrocycle, was found to be a highly active catalyst for air oxidation of HS(-) forming polysulfide species and H(2)O(2). The reaction provides a convenient method for the detection of the HS(-) generation rate of a H(2)S donor of medical importance.
