Direct irradiation of title compound 1 causes isomerization of the 1(10)-double bond to give the 1(10)Z,4E-isomer 2, due to selective energy transfer in the ß,-enone fragment formed by the carbonyl group and the 1(10)-double bond. Acetophenone-sensitized irradiation in n-hexane leads to the completely isomerized 1(10)Z,4Z-germacrone 3. 1(10)E,4Z-Germacrone could not be prepared photochemically.
