Effect of CHAPS and CPC micelles on Ir(III) catalyzed Ce(IV) oxidation of aliphatic alcohols at room temperature and pressure
TL;DR: In this paper, the authors studied the reaction of aliphatic alcohols in the presence and absence of surfactants in an acidic medium under pseudo-first-order conditions, [alcohol] T ǫ −[Ce(IV)] T. Ir(III)-salt used as catalyst had a significant effect on reaction rate.

Rate enhancement via micelle encapsulation for room temperature metal catalyzed Ce(IV) oxidation of formaldehyde to formic acid in aqueous medium at atmospheric pressure: A kinetic approach
TL;DR: In this paper, the micelles were found to accelerate the reaction rate and this effect has been explained by the partitioning of the reactants in micelle and also by considering the hydrophobic and electrostatic interactions between the surfactants and reactants.

Mechanism of Oxidation of the Antituberculosis Drug Isoniazid by Bromate in Aqueous Hydrochloric Acid Medium
TL;DR: In this paper, the authors investigated the reaction of isoniazid by bromate under pseudo-first-order conditions in acid medium and found that the reaction was accelerated by the hydrogen ion due to the various protonation equilibria of both the reactants.

Oxidation of alcohols, aldehydes, and carboxylates by the aquachromium(IV) ion
TL;DR: In this article, four methods have been developed to prepare aquachromium (IV), which is believed to be an oxo ion, CrO{sup 2+}. It readily converts Ph{sub 3}P to Ph{ sub 3}PO (k = 2.1 x 10{sup 3} L mol{sup 1} s{sup -1}) at 25 {degrees}C in 85% HClO/HClO (0.10 M HClClO{sub 4}

Hydride abstraction from 1,2-diols by the Pentaaqua(oxo)chromium(IV) ion
TL;DR: In this paper, a 2-equiv mechanism was proposed, in which CrO{sup 2+} abstracts a hydride ion from an alpha position in the primary and secondary diols and from a β position in pinacol.
