Copper(II) Chloride-Catalyzed Oxidation of a Styrene Oxide–Aniline Binary System in a Polar Solvent

In a mixed tert-butanol–chlorobenzene (9 : 1 vol) solution, the consumption of oxygen by a styrene oxide–aniline–copper(II) chloride ternary system is studied. For the first time, the formation of free radical particles is detected in copper(II) salt-catalyzed reaction of styrene oxide with the amine.
