The title α-diketone (1) was irradiated (λ > 340 nm) in a degassed benzene solution to afford a bicyclic ketone (2), 1,4-dipropylnaphthalene (3), and o-divinylbenzene (4); 1,4-dipropyl-2,3-dihydronaphthalene (6) being an intermediate which was trapped with dimethyl acetylenedicarboxylate to give the Diels-Alder adduct (5), and characterized by its visible absorption spectrum and its 1H nmr signal.
