Abstract
Abstract: The 4a-hydroperoxyflavin anion (4a-FlEtO~) spontaneously decays with a rate constant of 4.2 X sI (tert-butyl alcohol, 30" C). In the presence of the anions of 2, 3- dimethylindole (la-) and 5-methoxy-3-methyl-2-phenylindole (2a9 the pseudo-first-order rate constants (kobd) for disappearance of 4a-FlEtOL increase. Plots of I/kobsd vs. I/[la-] and 1/[2a-] are linear, and the limiting rate constants for 4a-F1Et02-disappearance at high ...
