Photochemical generation of free radicals from ketones

PHOTOCHEMICAL GENERATION OF FREE RADICALS FROM KETONES 

The assignment of the excited state of benzophenone as a triplet which could act as a sensitizer was made by Hammond and Moore in 1959 (equation 49)/ and this led to a great surge in radical study using photochemical techniques. The role of photoexcited benzophenone as a diradical initiator for benzaldehyde oxidation was previously shown explicitly by Backstrom in 1934 (equation 34).
