N2 - Irradiation induced fragmentation of 1,2‐dihydrophthalic anhydride (2) as well as of its precursor, 7‐oxonorbornen‐2,3‐dicarboxylic anhydride (1) yields benzene as the major product, accompanied by bicyclo[2.2.0]hex‐5‐ene‐2,3‐dicarboxylic anhydride (3) and tropone (5), in wave‐length dependent chemical‐ and quantum‐yields. It is shown that (2) is the key compound in the sequence, reacting from a singlet excited state and a biradical intermediate.
