19) will dissociate CO, Eq. (20), and react with CraqOO2 þ , Eq. (21). A small fraction may disappear in bimolecular radical self-reactions. The unusual kinetic traces under air-free conditions in Fig. 9b suggest that the chemistry in Eq. (21) produces additional equivalents of reducing intermediates resulting in an accelerated loss of CraqOO2 þ . In addition to CMe3CO (presumably in its hydrated form), any Cr2þ aq , produced either by slow homolysis of CraqOO2 þ or in the course of the CraqOO2 þ /CMe3CHO reaction, will also be involved in the loss of the superoxo complex.

This observation places a limit on the rate constant for the scavenging reaction with L1Ni2 þ at ! 108 MÀ1 sÀ1. 38 A. BAKAC Additional L1Ni3 þ was formed on a much slower time scale (several seconds) in the L1Ni2 þ /CraqO2 þ reaction, which was examined independently and found to have a rate constant of 1 Â 103 MÀ1 sÀ1. 5 Â 104 MÀ1 sÀ1 (196). 2 Â 108 MÀ1 sÀ1 (187), is responsible for the scavenging step observed by laser £ash photolysis. Clearly, the major portion of the two homolysis fragments, CraqO2 þ and NO2, had to di¡use into the bulk solution for the trapping by external reagents to take place.

46) (205), and kinetics that are second order in the total concentration of HNO2, and independent of [L2(H2O)RhOO2 þ ], consistent with the disproportionation of HNO2 being rate determining. 2L2 RhðH2 OÞ3þ 2 þ 3NO3 þ H ð46Þ The acid dependence, illustrated in Fig. 15, is consistent with HNO2 participating in an acid-independent and an acid-catalyzed reaction. Additional decrease in reactivity at higher pH is caused by the deprotonation of HNO2 which increases the proportion of the unreactive NOÀ 2 .
