Diels-Alder adduct under thermal conditions; the same product was obtained in much better yields under photochemical conditions. The reaction of cyclohexa-1,4-diene with diethyl azodicarboxylate under irradiation conditions gave 3-(diethylbicarbamyl)-cyclohexa-1,4-diene and diethyl hydrazodicarboxylate. Cycloocta-1,5-diene reacts with diethyl azodicarboxylate, both under thermal and photochemical conditions
