Irradiation (254 nm) of furan-benzene mixtures results in the formation of the 2,5;1',4'- and 2,3;1',2'-photocycloadducts (3) and (4) respectively as the major chemical processes: 2,3;1',3'- and 2,5;1',3'-cycloadducts are minor reaction products.Adduct (3) yields the isomer (4) by a reversible thermal or irreversible photochemical Cope rearrangement and both isomers undergo retroaddition on sensitised irradiation.Furan quenches the fluorescence of benzene but no exciplex emission is observed.A 1:1 photoadduct of thiophen and benzene is formed in trace amounts but only in the presence of proton donors.
