Observed rate constant kobs at 673 nm vs xanthene concentration for its oxidation by 41 at pH 4.7, 14.5 °C, yielding second-order rate constant k3 = (2.8 ± 0.3) × 106 M–1 s–1. Inset: correlation of k3 with C–H bond dissociation energy. Adapted from ref (212). Copyright 2009 American Chemical Society.
