The kinetics of oxidation of twenty one phenoxyacetic acids by quinolinium fluorochromate have been studied in binary solvent mixtures. Acrylonitrile has no effect on the rates of oxidation in dipolar protic solvent but in a aprotic solvent it decreases the oxidation rates. In both solvent systems there exists an equilibrium prior to the rate limiting step, followed by irreversible decomposition of the complex. The calculated rate constants correlate well with Hammett delta values. Suitable mechanisms have been proposed.
