Visible-light-mediated selenylation/cyclization reactions of diselenide with acrylimide derivatives: synthesis of selenosubstituted pyrrolidine-2,5-diones

We report a visible-light-mediated selenylation/cyclization reaction of selenium radicals generated from diselenides as radical sources with acrylimide derivatives, providing an effective route for the synthesis of symmetrical selenosubstituted pyrrolidine-2,5-diones.
