| Abstract: | The re-cycled irradiation of abietic acid above 300 nm with benzophenone and copper(ii) pivalate in toluene solution has resulted in conversion to dehydroabietic acid with a quantum yield ranging from 9.6 to 5.5. The high quantum yield may be attributed to the re-generation of benzophenone by means of the electron transfer reaction of benzophenone radical and to some additional reactions on formation of dehydroabietic acid. |
