The rate of electron self-exchange between chromium hexakis(2,6-diisopropylphenyl isocyanide) (Cr(CNdipp)6) and Cr-(CNdipp)6BF4 has been measured as a function of reactant concentration and temperature, -89 to +22°C, in CD2Cl2, by 1H NMR line broadening. The temperature dependence yields an enthalpy of activation of 1.5 ± 0.2 kcal/mol and an entropy of activation of -15.6 ± 0.6 cal/(mol K). These extrapolate to a rate constant of 1.8 × 108 M-1 s-1 at 25°C, one of the highest electron self-exchange rate constants known.
