Abstract
The use of indigo dyes as competiters to study the kinetics of oxidation reactions is reported. The kinetic model was theoretically investigated using the kinetic simulation program KinSim under conditions involving very limiting concentrations of the indigo dye relative to both the oxidant and the reductant. Complete kinetic results on the reaction of an oxidant with a reductant can be obtained indirectly from observing the absorbance changes due to the loss in the indigo dye at 600 nm (ε~600~∼2 × 10^4^ M^−1^cm^−1^). Experimental data from the oxidation of an olefin (cyclohexene) with m‐chloroperoxybenzoic acid in the presence of an indigo dye were used to check the validity of the kinetic model. © 2005 Wiley Periodicals, Inc.
