Fig. 4. Reactions of [FeIII2(μ-O2)(L3)2(S)2]4+ (6) (S = solvent) with 4-methyl-N,N-dimethylaniline (DMA). A) Time course of the decay of 6 monitored at 705 nm with DMA. B) Plot of k′obs (= kobs − kselfdecay) versus [substrate] for reactions of 6 with DMA at 278 K. C) Time course of the decay of 6 monitored at 705 nm with 2,6-di-tert-butylphenol (2,6-DTBP). D) Plot of k′obs (= kobs − kselfdecay) versus [substrate] for reactions of 6 with 2,6-DTBP at 278 K.
