Abstract
A photochemically initiated oxidation process for organic materials using only catalytic quantities of the photochemical agent by conducting the reaction in the presence of a compound of a variable valency metal (especially copper) in order to trap the photochemically produced radicals. The spent metal compound can be regenerated ready for trapping further radicals by contact with a source of oxygen.
