photo-oxidation of α-oxo-carboxylicacids and esters leads to the production of carbon dioxide. The yield of carbon dioxide is dependent upon the oxygen concentration. This, together with the fact that carbon dioxide evolution can be observed in the absence of oxygen, is in accord with the view that the decarboxylation reactions involve an initial dye-substrate interaction rather than a singletoxygen mediated

Methyl-α-keto-octanoate undergoes a TypeII reaction to give pent-1-ene and photophysical measurements show that this and the TypeII reactions of α-keto-acids occur, contrary to previous claims, from the excited singlet state.
