The acyl derivatives of 1 with the acyl group linked to aryl, vinyl etc. give on photolysis carboxy radicals.These radicals, by attack on the thiopyridone function, afford thio-peresters which are the real precursors of the anhydrides observed before.The benzoyloxy radical from 2 can be trapped by ethylvinyl ether to give adduct 14 in promising yield.
