Abstract

original image

Easy peasy: The title reaction employs N-formylsaccharin, which is an easily accessible crystalline compound, as an effective CO source. The reactions proceed with a small excess of the CO source at moderate temperatures and were successfully applied to a wide range of aryl bromides. DMF=N,N-dimethylformamide, dppb=1,4-bis-(diphenylphosphino)butane.
