Abstract

The oxidation of cyclohexene to the epoxide is catalysed by Ru(III)-EDTA in a 50% ethanol/water solution at 30°C in the pH range 1-3 (μ=0.1 M KCl). The observed reaction rates for the oxidation of cyclohexene are first order with respect to Ru(III)-EDTA and cyclohexene, and one-half order with respect to molecular oxygen. A mechanism has been proposed for the oxidation of cyclohexene by molecular oxygen catalysed by Ru(III)-EDTA. The turnover number for the epoxidation of cyclohexene by molecular oxygen catalysed by Ru(III)-EDTA is 200 mol (mol catalyst) −1min−1.
