The title complex reacts with 1,3-diphenylisobenzofuran to afford the Diels-Alder adduct [CpFe(CO)2(η1-N-1,4-diphenyl-1,4-epoxy-1,4-dihydronaphthalene-2,3-dicarboxyimidato)] 2 in nearly quantitative yield. The competitive experiment showed that this reaction is around three times slower than the reaction of the parent maleimide with 1,3-diphenylisobenzofuran. The X-ray crystal structure of 2 has been determined. It revealed a scrolled configuration resulting from an endo transition state in Diels-Alder reaction and from various hydrogen bonds and π-π interactions.
