a) Time-resolved UV-vis spectral changes observed in the reaction of MnV(O)(TBP8Cz) (13 μM) with PPh3 (0.16 mM) in CH2Cl2 at 25 °C. Inset: changes in absorbance vs time for the growth of MnIII(TBP8Cz) (685 nm) (red circles) and decay of MnV(O)(TBP8Cz) (635 nm) (blue circles) with the best fit lines (black). Plots of pseudo-first order rate constants (kobs) vs [triarylphosphine] for b) para-substituted triarylphosphines and c) para, meta and ortho-tolyl substituted phosphines.
