The mechanisms of aqueous oxidation-reduction interactions between Cr (VI) and substituted phenols (RArOH) were characterized by kinetic analysis and determinations of reaction products and intermediates. A rapid, preoxidative equilibrium between HCr04-and RArOH forms chromate ester intermediates, as verified by spectroscopy. The subsequent ratelimiting ester decomposition proceeds via innersphere electron transfer. The overall ...
