Oxidation of DTT^red with H₂O₂ in the presence of compounds 10, SLC-0111, and 22. Reaction conditions: [DTT^red]₀ = 0.14 mM, [H₂O₂]₀ = 0.14 mM, [catalyst] = 0.014 mM, CD₃OD = 1.1 mL. ¹H NMR spectra were measured at variable reaction time at 25 °C. The relative populations of DTT^red and DTT^ox were determined by integration of the ¹H NMR signals. In the control experiment the reaction was run with no catalyst. Reported are the mean ± SD values of three separate experiments.
