The light-induced Diels-Alder addition of maleic anhydride to naphthochrysene (1) yields the same dicarboxylic anhydrides 2 and 4 as the thermal Diels-Alder addition. 4 is further isomerized by light to give the fluorenone carboxylic acid 6, as was revealed by isolation of compounds 7 and 8 after decarboxylation of the mixture 2 + 4.Analogously, 12 is formed by irradiation of the dicarboxylic anhydride 10; decarboxylation of 12 yields 13 and 14.The simpler systems 15 and 17 did not undergo an analogous light-induced isomerization.Photophysical examination of 4, 10, 15, and 17 gave no clue to the reasons for this difference in behaviour.

1-Phenylnaphthalene-2,3-dicarboxylic anhydride (I) reacts with hydroxylamine hydrochloride to give N-hydroxy-1-phenylnaphthalene-2,3-dicarboximide (II) which on pyrolysis forms 1-phenylnaphthalene-2,3-dicarboximide (III).The imide III is also obtained by
