The effect of triton X-100 micelles on the aquation of Fe(Me₄phen)²⁺₃ has been investigated with triton X-100 as solvent. In liquid triton X-100, over a range of [H₂O]_T(0.2–2.0 mol dm^–3), significant rate enhancement factors of 35–140 are observed. Acid inhibits the rate of aquation at fixed [H₂O]_T. A mechanism based on effective solvent participation in a chemical environment similar to that in reversed micelles is proposed in liquid triton X-100 with dispersed water pockets. This mechanism predicts direct H₂O substitutions into the coordination sphere of Fe(Me₄Phen)²⁺₃ in the highly polar water pockets or cavities where the Fe^II complex molecules are solubilized. Changes in the tumbling rate, mobility, structure, nucleophilicity and activity of water are suggested to account for the observed changes in the rate of aquation as a function of [H₂O]_T, in the peculiar chemical environment of the water pockets. All k_ψ–[H₂O]_T profiles are structured and exhibit maxima with k_ψ(max) shifted to progressively higher [H₂O]_T as the fixed concentration of [H⁺]_T is increased.
