In the photolysis of a benzene solution of <I>N</I>-methyl-1,2-naphthalenedicarboximide (<B>5</B>) in the presence of dienes, i.e., 2,3-dimethyl-1,3-butadiene and 1,3-butadiene, insertion of one of the double bond in the dienes into a C(=O)–N bond of <B>5</B> was observed to give naphthazepinediones. These products were found to convert further into cyclobutanes and α,β-unsaturated ketones via photochemical intramolecular cycloaddition and via hydrogen migration, respectively.
