The radiochemical cyclodimerization of 1,3-dienes can lead to syn- and anti-C/sub 4/-cycloadducts of the Diels-Alder type. The previously unknown exo- Diels-Alder dimer (V) of 1,3-cyclohexadiene was obtained by gamma irradiation of 1,3-cyclohexadiene in benzene and by irradiation in sensitized and unsensitized photoreactions. The same product was obtained as with thermal cyclodimerization and ring isomerization. Diels-Alder adducts could be formed radiochemically by different chemical relay mechanisms, which require the participation at times of at least 3 molecules. For the pure thermal uncatalyzed Diels-Alder dimerism of 1,3-cyclohexadiene the trimolecular substrate relay mechanism is discussed. (tr- auth)
