Intra- and intermolecular copper(I)-catalyzed [2+2] photocycloaddition reactions of nonconjugated alkenes can be achieved efficiently in room-temperature ionic liquids such as [tmba][NTf 2 ]. The ionic liquid can be recovered and recycled. No cycloadduct could be isolated when the same reaction is carried out under identical conditions in [bmim][NTf 2 ], which undergoes extensive decomposition.
